	Experimental Search for Light Sterile Neutrinos with the SOX experiment			WG5-(oral)  cancelled ()
	Sterile neutrinos are hypothetical neutrino-like particles insensitive to the standard weak interaction. The could mix with the active neutrinos, however. In the last two decades several short baseline neutrino experiments reported results that could be interpreted as a hint for a sterile neutrino in the eV mass range. I will discuss the search for eV-scale sterile neutrinos that will be carried out with the SOX Experiment, which consists of an intense 144Ce antineutrino source deployed next to the large liquid scintillator detector Borexino at the Laboratory Nazionali del Gran Sasso. Combination of the anticipated SOX results with other experiments will be discussed.   (28/03/2016)

	The ERC ENUBET Project: high precision neutrino flux measurements in conventional neutrino beams			WG3-(oral)  accepted (WG1+WG2+WG3)
	The challenges of precision neutrino physics require measurements of absolute neutrino cross sections at the GeV scale with exquisite (1%) precision. This precision is presently limited to by the uncertainties on neutrino flux at the source. A reduction of this uncertainty by one order of magnitude can be achieved monitoring the positron production in the decay tunnel originating from the K_e3 decays of charged kaons in a sign and momentum selected narrow band beam. This novel technique enables the measurement of the most relevant cross-sections for CP violation (nue and antinue) with a precision of 1% and requires a special instrumented beam-line. Such non-conventional beam-line will be developed in the framework of the ENUBET Horizon-2020 Consolidator Grant, recently approved by the European Research Council. In this talk, we will present the Project, the first experimental results on ultra-compact calorimeters that can embedded in the instrumented decay tunnel and the adv ances on the simulation of the beamline. We also discuss the detector and accelerator activities that are planned in 2016-2021. Note: talk on behalf of the ENUBET Collaboration Note: since the contents of the talk includes items that are interesting both to WG2 and WG3, we’d like to give the talk in a joint WG2+WG3 session   (10/04/2016)

	Reason for T2K to run in dominant neutrino mode for detecting CP violation			WG1-(oral)  poster (WG1)
	The long-baseline experiment T2K in Japan has collected data in the neutrino mode corresponding to an exposure of 6.57 \times 10^{20} POT (Protons on Target) and currently it is running in the antineutrino mode. The main aim of the antineutrino run is to measure the leptonic phase $\delta_{CP}$ which may help to understand the matter-antimatter asymmetry of the universe. In this talk I will show that in T2K, antineutrinos are required only for removing the wrong octant solutions which in turn improves the CP sensitivity. If however the octant is known then pure neutrino run is capable of giving the maximum CP sensitivity. Thus it is worthwhile to study if the T2K antineutrino run can be reduced by the antineutrino runs of the other experiments, so that T2K can run in dominant neutrino mode to extract the best CP sensitivity. In this talk I will also discuss the possibility of the antineutrino component of NO$\nu$A and the atmospheric neutrino experiment ICAL@INO for compensating the antineutrino run of T2K.   (15/04/2016)

	Hadron Production Measurements with NA61/SHINE for Neutrino Experiments			WG1-(oral)  accepted (WG1+WG2)
	We present latest results on hadron production in proton-carbon interactions at 31GeV/c measured by the NA61/SHINE experiment at CERN SPS. Data have been taken with a thin 2cm carbon target and with a 90 cm long replica of the T2K target. They aim at improving the precision of neutrino flux predictions in the T2K long baseline experiment. Recently published new measurements for the thin target are based on the largest dataset and include spectra of charged hadrons π^±, K^± and protons as well as neutral hadrons Λ^0 and K^0_s. Results combine different analysis techniques to provide a better precision in the region measured so far and to extend the coverage in momentum and polar angle in the region of interest to T2K. We also report on the new published π^± results for the T2K replica target. Measurements with the replica target have the advantage to cover at the same time particles originating from primary interactions as well as particles from hadron re-interactions inside the target. The dedicated method that has been developed to include these measurements in the T2K flux simulations will be discussed followed by published and an ongoing analysis results for the large dataset taken with the replica target that is expected to further improve the precision of flux predictions. The success of the NA61/SHINE measurements for T2K resulted in the approval of similar program for Fermilab neutrino physics and here plans for the next few years will be discussed.   (21/04/2016)

	Will atmospheric neutrino experiment at Hyperkamiokande see non-standard interaction effects?			WG5-(oral)  accepted (WG5)
	It has been pointed out that the values of the mass squared difference from the solar and KamLAND experiments are different, and one of the possible explanations for the difference is due to the non-standard flavor dependent interaction in propagation of neutrinos. We show that the future atmospheric neutrino experiment at Hyperkamiokande has a chance to see signals of such a non-standard interaction at some significance, if the difference between the two values of the mass squared difference is caused by the non-standard interaction.   (22/04/2016)

	Studies for the MOMENT and EMuS target system			WG3-(oral)  accepted (WG3)
	We describe the latest studies for the pion/muon capture system at MOMENT (a muon-decay medium-baseline neutrino beam facility). It uses a high-power proton beam of 15 MW from a continuous wave linac that poses a radiation challenge for the target system which consists of a liquid mercury jet immersed inside a superconducting solenoid. Topics include updated studies of the pion/muon capture and the radiation effects induced by the high power. Then we continue with studies for the target system of EMuS (an experimental muon source) project at China Spallation Neutron Source (CSNS) that uses a proton beam of 4 kW at 1.6 GeV in order to produce an intense muon beam. Similar to MOMENT, it consists of a graphite target inside a superconducting capture solenoid. Topics include optimization of the capture system parameters for muons and pions, the latter in order to examine the possibility of a short-baseline neutrino experiment.   (25/04/2016)

	Results from the OPERA experiment in the CNGS beam			WG1-(oral)  accepted (WG1)
	The OPERA experiment at the Gran Sasso underground laboratory has recently established nu_mu -> nu_tau oscillations in appearance mode with a significance of 5.1 sigma thanks to the observation of five signal candidate events in a sample with a signal-to-background ratio of about ten. The nu_tau data analysis will be discussed, with emphasis on the background constraints obtained by using dedicated data-driven control samples. The analysis of the nu_mu->nu_e channel, formerly based on the first two years of run, has been extended over the full data set with a more than twofold increase in statistics. The implications of the tau neutrino and electron neutrino samples in the framework of the 3+1 sterile model will be discussed. The Collaboration is also focusing on the characterization of nu_tau-like interactions failing the kinematical analysis defined in the experiment proposal to obtain a statistically enhanced, lower purity, signal sample. One such interesting neutrino interaction with a double vertex topology will be presented. Finally, topics in the analysis of the OPERA cosmic ray sample will be covered.   (25/04/2016)

	Searching for neutrinoless double beta decay with bolometers			WG5-(oral)  accepted (WG5)
	Neutrinoless double beta decay is the only practical probe to the Majorana nature of neutrinos. Large mass bolometer arrays offer superb energy resolution, versatility in isotope choice, and large isotope mass at a reasonable cost. The CUORE experiment will search for neutrinoless double beta decay of Te-130 using a ton-scale bolometer array with 5 keV resolutions. It will be sensitive to an effective neutrino mass of 40-100 meV and one of the most competitive experiments under construction. CUPID, a future bolometer array with photon readout will push the sensitivity by another factor of 5 to cover the inverted mass hierarchy phase space. In this talk, I will present the latest status and physics reach of CUORE as well as conceptual design and R&D effort towards CUPID.   (27/04/2016)

	Microwave Spectroscopy of the Muonium Atom at Zero and a High Magnetic Field.			WG4-(oral)  accepted (WG4)
	The muonium is a hydrogen-like atom composed of a positive muon and an electron. Purely leptonic feature of this exotic atom allows rigorous test of bound-state QED (quantum electrodynamics) as well as precise determination of the magnetic moment of muon and hence its mass. The ratio of magnetic moments between muon and proton is an indispensable input parameter in deducing the anomalous magnetic moment (g − 2), an important physical quantity for the test of the Standard Model and beyond. MuSEUM Collaboration aims at a precision microwave spectroscopy of the ground state of the muonium atom at J-PARC in Japan. High-intensity pulsed muon beams will be stopped in a krypton gas target in a microwave cavity to form muonium atoms. Resonant spin-flip transitions between hyperfine sublevels of the atom will then be detected by observation of positrons emitted favorably in the direction of the muon spin at the time of the muon decay. The center frequency of the resonance will be determined at an ultimate relative precision of the order of 10 ppb (10^-8). We are planning our measurement under two complementary conditions: one at a high magnetic field of 1.7 T, and another at zero field. The major source of the uncertainty was statistics in the past experiments, which can be reduced with the high-intensity beam, while systematic uncertainties will be minimized by various improvements in our experimental setup and careful considerations with computer simulations. Extensive studies have been done for uncertainties arising from microwave power fluctuations, magnetic field inhomogeneity, muon stopping distribution and gas-density shift of resonance frequencies. Our recent progresses and results will be presented in the oral talk.   (28/04/2016)

	Development of the muon linac for the muon g-2/EDM experiment in J-PARC			WG4-(oral)  accepted (WG4)
	The muon anomalous magnetic moment (g-2) has a difference of approximately three standard deviations between the measured value by the BNL E821 experiment and the standard model (SM) prediction. More precise measurement is required since it might imply an evidence of the physics beyond SM. The J-PARC E34 experiment aims to measure muon g-2 with a statistical uncertainty of 0.1 ppm and search for the muon EDM with novel techniques. The muon acceleration is one of the most important techniques for our measurement. The muon-dedicated linac which consists of RFQ followed by several types of RF cavities, is being developed. The muon deceleration with a thin metal foil and an electro-static lens are required in order to demonstrate the muon RFQ acceleration which will be first case in the world. First, the conventional surface muons with an energy of 4 MeV are injected to the foil and decelerated to sub-keV. Then the decelerated muons are extracted and accelerated to 5.6 keV by the electro-static lens. Finally the muons will be injected to the RFQ and accelerated to 0.34 MeV. We succeeded in the muon deceleration and electro-static acceleration in February 2016 at J-PARC MLF and we are ready for the muon acceleration with RFQ. This talk presents the current status of the experimental components, especially the muon acceleration developments.   (28/04/2016)

	Tau-neutrino production study at CERN SPS: Novel approach by the DsTau experiment			WG2-(oral)  accepted (WG2)
	The tau-neutrino CC cross section has never been well measured. There has been only one measurement by the DONuT experiment with a systematic uncertainty larger than 50%, mainly due to uncertainties in the Ds differential production cross section in high energy proton interaction. The DsTau collaboration proposes to study tau-neutrino production and the energy distribution by analyzing Ds -> tau events in 400 GeV proton interactions. By employing the state-of-the-art emulsion particle detector technologies, we will analyze 10^8 proton interactions and detect the double kink topology of Ds -> tau -> X decays. Accomplishing this new measurement, we will re-evaluate the tau-neutrino cross section with the data from DONuT and test lepton universality in neutrino CC interactions. Furthermore, it will provide data useful for future tau-neutrino experiments. In this talk, we report an overview of the experiment and the planned prototype test in 2016.   (30/04/2016)

	EMuS in CSNS			WG3-(oral)  accepted (WG1+WG2+WG3)
	MuSR is a useful tool which use muons as magnetic probes in matter. There are several MuSR running around world. Now a R&D program named EMuS had been approved to setup a new MuSR in China. The EMuS will be located in CSNS, Dongguan. Use 4KW/20KW 1.6GeV proton beam from CSNS hit target to generate surface muons and pions, then secondary particels will be collected and transfered. Besides polarized muons used as MuSR, neutrinos decayed from pions and muons are planned to be used to do various experiments. Unlike those previous MuSR, EMuS adopted adiabatic particle capture system concept from Neutrino Factory and COMET, so a higher intensity muon beam is expected to be achieved. This would make EMuS a place with good competitiveness for material analysis and neutrino physics. The layout of the project, design of the proton beamline, target station, MuSR beamline, neutrino muon beamline and MuSR will be reported.   (30/04/2016)

	High power beam operation of J-PARC Main Ring synchrotron (replaced by abstract #35)			WG3-(talk)  replaced by #35 ()
	The main ring (MR) of the Japan Proton Accelerator Research Complex (J-PARC) has been providing 30-GeV proton beams for elementary and nuclear physics experiments since 2009. The beam power of 390 kW with 2e14 protons per pulse (ppp) are provided for the neutrino oscillation experiment in the cycle of 2.48 s. The beam power has been increased 1.5 times in the last 2 years. Main efforts in the beam tuning are to minimize beam losses and to localize the losses at the collimator section. Recent improvements are the corrections of resonances near the operation setting of the betatron tune, and adopting the 2nd harmonic rf operation to reduce the space charge effect with a larger bunching factor. In order to optimize all tuning nobs, beam instabilities have been sufficiently suppressed with controlling chromaticity correction pattern and transverse feedback systems. We plan to achieve the target beam power of 750 kW with 2e14 ppp in JPY 2018 by making the cycle time faster to 1.3 s. To enable the faster cycle, we are going to upgrade new power supplies of main magnets, rf cavities, injection and extraction devices, and collimator capacity. The possibility for the beam power beyond 2e14 ppp is being explored with new settings of the betatron tune. To accelerate 6.8e13 protons per 2 bunches (2.7e14 ppp equivalent) was successfully demonstrated without using the 2nd harmonic rf operation. We are constructing a new scenario to achieve the target beam power of 1.3 MW.   (01/05/2016)

	Impact of sterile neutrinos on CP and mass hierarchy at long baselines			WG5-(oral)  accepted (WG1+WG5)
	My talk will be based upon 1. JHEP 1511 (2015) 039 and 2. an upcoming paper. With the Deep Underground Neutrino Experiment (DUNE) as an example, we show that the presence of even one sterile neutrino of mass $\sim$1 eV can significantly impact the measurements of CP violation and mass hierarchy in long baseline experiments. Using a probability level analysis and event rate calculations, we discuss the large magnitude of these effects, and show how they translate into significant deviations on the chisquare level at DUNE and also at NOvA, T2K and T2HK. Our results demonstrate that measurements which, when interpreted in the context of the standard three family paradigm, indicate CP conservation at long baselines, may, in fact hide large CP violation if there is a sterile state. Similarly, any data indicating the violation of CP cannot be properly interpreted within the standard paradigm unless the presence of sterile states of mass O(1 eV) can be conclusively ruled out. Our work underscores the need for a parallel and linked short baseline oscillation program and a highly capable near detector for DUNE, in order that its highly anticipated results on CP violation in the lepton sector may be correctly interpreted.   (01/05/2016)

	Electron-antineutrino appearance search at the T2K experiment			WG1-(oral)  accepted (WG1)
	T2K is a long-baseline neutrino experiment that aims to measure theta_23, Delta-m^2_32 and theta_13 through muon-neutrino disappearance, electron-neutrino appearance and their antineutrino equivalent channels. In 2013, T2K observed electron-neutrino appearance in a muon-neutrino beam for the first time. Compared to the constraints on theta_13 provided by the reactor experiments in the antineutrino sector, T2K observed a higher number of oscillated electron neutrinos, which tends to favour a maximal CP-violation effect. T2K is currently taking data in antineutrino mode. In this presentation, we will show the latest results of electron-antineutrino appearance at T2K, using the full antineutrino data set. Both rate and rate+shape analyses will be presented. Finally, we will compare neutrino and antineutrino appearance results in order to show the latest constraint on the CP violation parameter.   (01/05/2016)

	Neutrino CC0pi double-differential cross section on hydrocarbon at the T2K on-axis detector.			WG2-(oral)  pending ()
	The charged-current interactions with no pion emission (CC0pi) are one of the most important processes in long-baseline neutrino experiments: they are, for instance, the dominant channel in T2K (∼ 70%). Relatively large discrepancies have been observed between the CC0pi cross- section measurements in various experiments (MiniBooNE, MINERvA, NOMAD, T2K). The uncertainty on the modeling of these neutrino interactions is today one of the dominant systematic uncertainties on the measurement of neutrino oscillations in T2K. It is therefore crucial to improve the accuracy of the CC0pi neutrino cross section to reach the precision required for the future search for CP violation in neutrino oscillations. The Proton Module (PM) is a detector located on-axis in the T2K experiment at 280 m from the proton beam target used to produce the neutrino flux. Since the neutrino flux crossing the PM ranges from 400 MeV to 3 GeV, it covers both the MiniBooNE energy region (< 2 GeV) and the higher energy region (> 2 GeV), as for MINERvA and NOMAD. Hence the PM is ideally adapted to probe the observed discrepancies between the CC0pi measurements performed in the mentioned experiments. In this presentation, we will show the first measurement in the PM of the double differential CC0pi neutrino cross section using muon angle and momentum. We will also present further constraints on the neutrino cross-section models combining the information of the outgoing lepton and nucleons, such as the kinematics imbalance in the plane transverse to the neutrino direction.   (01/05/2016)

	The search for sterile neutrinos at future particle colliders			WG5-(oral)  canceled ()
	Sterile neutrinos are among the most attractive (but also hardest to test) extensions of the SM to generate the light neutrino masses observed in neutrino oscillation experiments. When the sterile (heavy) neutrinos have masses around the electroweak scale, they can be efficiently searched for at future particle colliders. In this talk I review the most efficient search channels, present updated estimates for future sensitivities of the planned European (FCC), Chinese (CEPC, SppC) and Japanese (ILC) projects, and compare those with the present bounds from existing experiments. Emphasis is put on the lepton collider phenomenology.   (01/05/2016)

	Latest Results from the Daya Bay Reactor Neutrino Experiment			WG1-(oral)  accepted (WG1)
	The Daya Bay Reactor Neutrino Experiment was designed to measure θ13, the smallest mixing angle in the three-neutrino mixing framework, with unprecedented precision. The experiment consists of eight functionally identical detectors placed underground at different baselines from three pairs of reactors, a unique configuration that minimizes systematic uncertainties and cosmogenic backgrounds. In 2012 Daya Bay made the first definitive observation of a non-zero value of θ13, a result that opened the door for a rich program of future neutrino oscillation physics. With a growing dataset that constitutes the largest sample of reactor antineutrino interactions collected to date, Daya Bay is able to greatly improve the precision on θ13 and to make an independent measurement of the effective mass splitting in the electron antineutrino disappearance channel with a precision comparable to that from accelerator experiments. Daya Bay can also perform a number of other groundbreaking m easurements, such as a high-statistics determination of the absolute reactor antineutrino flux and spectrum, as well as a search for sterile neutrino mixing, among others. The most recent results from Daya Bay will be discussed in this talk, alongside the current status and future prospects of the experiment.   (01/05/2016)

	Neutrino Induced Neutral Current Coherent Pi0 Production in The NOvA Near Detector			WG2-(oral)  accepted (WG2)
	The NOvA experiment is a long-baseline neutrino oscillation experiment designed to measure the rate of electron neutrinos appearance in a muon neutrino beam. It consists of two finely segmented, liquid scintillator detectors at 14 mrad off-axis in the NuMI beam. The NOvA Near Detector, located at Fermilab, provides an excellent opportunity to study neutrino-nucleus interactions which are important for neutrino oscillation measurements. This presentation will present one of the first such measurements from NOvA: neutrino-induced coherent-Pi0 production. Neutrinos can coherently interact with the target nucleus via neutral current exchange and produce a single, forward Pi0, which makes background to the NuE appearance measurement. The analysis measures the coherent-Pi0 kinematics and cross-section and compares to model predictions, and thusly also provides a data constraint on Pi0 production in the neutral current resonance and deep-inelastic interaction.   (02/05/2016)

	Hierarchy sensitivity of NOνA in light of T2K νe appearance data			WG1-(oral)  cancelled (WG1)
	The $\nu_e$ appearance data of T2K experiment has given a glimpse of the allowed parameters in the hierarchy-$\dcp$ parameter space. In this paper, we explore how this data affects our expectations regarding the hierarchy sensitivity of the \nova experiment. For normal hierarchy and $\dcp$ in the lower half plane, the hierarchy sensitivity of \nova is unaffected by the addition of T2K data. For inverted hierarchy and $\dcp$ in the upper half plane, addition of T2K data helps in ruling out the wrong hierarchy at 95$\%$ confidence level. For the unfavourable combinations, \nova data gives degenerate solutions. Among these degenerate solutions, T2K data prefers inverted hierarchy and $\dcp$ in the lower half plane over normal hierarchy and $\dcp$ in the upper half plane. Hence, addition of the T2K data to NO$\nu$A creates a bias towards inverted hierarchy and $\dcp$ in the lower half plane irrespective of what the true combination is.   (04/05/2016)

	PACIFIC NEUTRINOS: towards a high precision measurement of CP violation ?			WG1-(oral)  accepted (WG1)
	A remarkable conjunction has recently emerged from the establishment of Fermilab as a worldwide long term neutrino facility, the development of the deep sea environmental observatories NEPTUNE and OOI offshore of Vancouver and Seattle, and the maturation within the ANTARES/KM3NeT consortia of high granularity deep sea cerenkov detection technologies suited for neutrino measurements in the few GeV domain (ORCA option). In an attempt to exploit this conjunction, we will present an investigation of the potential of a o(10Mton) submarine neutrino cerenkov detector based on KM3NeT-like optical modules, implemented within the NEPTUNE/OOI infrastructure in a neutrino beam issued from FNAL. The study extrapolates from the LBNO study corresponding to a 25% shorter baseline, and from the ORCA detector sensitivity studies of the KM3NeT LOI. A possible roadmap towards a project will also be outlined.   (19/05/2016)

	About the dark matter			WG5-(poster)  refused ()
	We have introduced earlier the Dual World Theory (DWT) as an application of our Extended Quantum Particle Model (EQP). We have pointed out that the antimatter which was formed during the Big Bang (which is a decay of darkeon matter to a + and – valued (that is normal and anti) space dimension) is part of the dark matter or Dark Universe. The distribution of it is now measured by gravitational effects. The inverse scaling matter is called the Inversum. We state that as a consequence of the Grand Fermat’s Conjecture (Fermat – Wiles Theorem) one can get that no exists the 3 dimensional Euclidean space. In case of d=3 a non Euclidean fractal spacetime with bottlenecks and gaps exists which provide a curved spacetime for quantum particle states at small scales and low energies. Before Big Bang there should happen a separation of normal scaling and antiscaling darkeons which could be an explosion like effect. Later the normal scaling darkeon matter turned to SECP/SEMP objects which dissociated to matter and antimatter. The inverse scaling antimatter started to expand and as a consequence the space of visible matter Universe followed this expansion due to gravitational coupling. This was the Big Bang itself. A similar process happened in the antiscaling darkeon matter, so there happened a double Big Bang in fact. These four matter universes has equal mass which provides a ¼ : ¼ : ¼: ¼ mass ratio. This model is supported by the strong experimental asymmetry of the visible and total dark matter. We suppose that somehow the two inverse scaling Inversums are or became connected at least gravitationally and so contribute to the recent total mass measurements of the dark matter. Considering the experimental ratios, our above model provides within 15% deviation about 5 % visible barionic matter and 21% dark matter for the world. This means that we predict 26% matter and 74% dark energy content for the cosmological world. The large scale dark matter phenomena already can be investigated by their gravitational wave effects, too. A number of interesting questions arise. Eg. if the experimental ratio of visible and dark matter considerably asymmetric it might be a sign that a second much smaller double Big Bang happened after (or before) the original Big Bang. This second event can have an overlap in space with the original Universes. The main result of our model is that on the base of physical considerations we could predict theoretically the experimental cosmological mass ratios of the visible and dark matter and matter and energy content. The universes predicted by us contain considerable dark matter. In certain scenarios dark matter can be related to neutrinos (majoron, sterile neutrino,..) or neutrino mass generation processes. This way cosmic neutrinos can carry important information about these very large scale events and processes (the two double BigBangs and universes and among them the position of Eridania Universe because recently as we assume mainly by gravitational effects we have bulk information ) , may contribute to fix the multiverse space, so it is important to investigate it by these aspects, too.   (29/05/2016)

	Testing the Dark Matter Scenario for PeV Neutrinos Observed in IceCube			WG5-(oral)  accepted (WG5)
	Late time decay of very heavy dark matter is considered as one of the possible explanations for diffuse PeV neutrinos observed in IceCube. We consider implications of multimessenger constraints, and show that proposed models are marginally consistent with the diffuse gamma-ray background data. Critical tests are possible by a detailed analysis and identification of the sub-TeV isotropic diffuse gamma-ray data observed by Fermi and future observations of sub-PeV gamma rays by observatories like HAWC or Tibet AS+MD. In addition, with several-year observations by next-generation telescopes such as IceCube-Gen2, muon neutrino searches for nearby dark matter halos such as the Virgo cluster should allow us to rule out or support the dark matter models, independently of gamma-ray and anisotropy tests.   (30/05/2016)

	Targets for high-intensity muon sources for cLFV experiments			WG4-(either)  accepted (WG3+WG4)
	Physical stability of the pion production target is indispensable for producing high-intensity muon beam for the use in cLFV experiments. Different kinds of materials have been investigated for this purpose along with suitable cooling methods. Recently light material such as graphite has been used in many facilities thanks to its stability at high temperature while a new composite material, silicon carbide (SiC) is also being studied. Silicon carbide is as refractory as graphite and has a density larger than graphite. We report our R&D plan of silicon carbide to be used as a pion production target at J-PARC.   (31/05/2016)

	Review of experimental status on cLFV experiments (plenary)			WG4-(oral)  accepted (Plenary)
	Charged Lepton Flavor Violation (cLFV) is strictly forbidden in the Standard Model. Even if we include the effect of the neutrino oscillation in the Standard Model, the probability of cLFV is extremely small to be observed an experiment. Thus any experimental indication of cLFV in charged lepton decays is thought to be a stunning evidence of the new physics beyond the Standard Model. In this presentation, we review the physics motivation of cLFV searches and status of ongoing experiment with a focus on experiments using high intensity muon beams.   (31/05/2016)

	Status and future prospects for charged Lepton flavor violation (cLFV) searches at LHCb			WG4-(oral)  accepted (WG4)
	In the Standard Model the different lepton families couple universally to gauge bosons. Therefore, the ratio of branching fractions of decays with different lepton flavours is predicted with a very good accuracy. The universality of lepton couplings has been tested using the LHCb Run 1 dataset, resulting in some tensions with respect to the predicted values. Lepton non-universality would be a major departure from the Standard Model and may also be accompanied by lepton flavour violation. Recent tests of lepton flavour universality and searches for lepton flavour violation decays at LHCb will be presented. disclaimer: the abstract is submitted by the LHCb Speakers’ Bureau chair on behalf of the LHCb collaboration.

	Testing the Direct and Indirect Unitarity Violation at a Neutrino Factory			WG5-(oral)  accepted (WG5)
	The mixing of existing active neutrinos with possible light or heavy sterile ones is defined as direct or indirect unitarity violation of the effective 3x3 leptonic mixing matrix. Sensitivity potential of unitarity violation parameters with a neutrino factory is presented in a minimal hybrid framework with one light and one heavy sterile neutrinos. Possibility of discriminating between the direct and indirect unitarity violation is discussed and non-trivial sources of leptonic CP violation are illustrated. Finally we stress that probing the generic feature of unitarity violation and origin of leptonic CP violation could constitute the driving force for the neutrino factory.   (01/06/2016)

	Final results of the MEG experiment			WG4-(oral)  accepted (WG4)
	The MEG experiment at the Paul Scherrer Institut searched for the lepton-flavour violating decay mu -> e gamma, practically forbidden in the Standard Model but strongly enhanced in many of its extensions. With the analysis of half of the collected statistics, the MEG collaboration set the most stringent upper limit on the branching ratio of the decay to be 5.7 x 10^{-13} at 90% confidence level, with an associated sensitivity of 7.7 x 10^{-13}. In this contribution the analysis of the full dataset collected from 2009 to 2013 will be presented: with a doubled statistics and an improved analysis technique, the resulting associated sensitivity is 5.3 x 10^{-13}. The implications of the MEG result in the context of lepton flavour violation will also be discussed and promising future directions will be highlighted.   (01/06/2016)

	The Jiangmen Underground Neutrino Observatory (JUNO) is a liquid scintillator detector aiming to determine the neutrino mass hierarchy and to perform precision measurements of the neutrino mixing parameters by detecting reactor antineutrinos at a baseline of 53km. JUNO physics programme also includes the detection of supernova neutrinos, geoneutrinos and solar neutrinos. The central detector is a 35.4 meter diameter acrylic sphere supported by steel struss, holding 20 kt liquid scintillator monitored by 17k 20'' MCP-PMT, resulting in ~75% photo-coverage. This design is tailored to reach an extremely high light yield (1200 PE/MeV) pivotal to achieve the unprecedented energy resolution of 3% at 1 MeV. Introducing 34K 3'' PMTs brings the multi-calorimeter concept into the reality to help event reconstructions and reduction of impacts by the non-stochastic component in the energy response. In this talk we will update the recent progress in JUNO.   (09/06/2016)

	ZICOS – New project for neutrinoless double beta decay experiment using Zr-96 in liquid scintillator			WG5-(oral)  cancelled ()
	A liquid scintillator containing a tetrakis (isopropyl acetoacetato) zirconium (Zr(iprac)4) has been developed for the Zirconium Complex in Liquid Scintillator (ZICOS) experiment which is new project of neutrinoless double beta decay search. We are aiming to develop a detector which has a good energy resolution (3.5 % at 3.35 MeV), a large light yield (60% of BC505 ) and a low background rate (0.1 counts/tonne⋅ year) with several hundred kg of Zr-96 isotope. A Zr(iprac)4 has high solubility (over 30 wt.% ) in anisole, which is used for the solvent of our liquid scintillator. We have measured performances of the liquid scintillator containing 10 wt.% concentration of a Zr(iprac)4, and obtained 48.7 ± 7.1 % of the light yield of BC505 and the energy resolution of 4.1 ± 0.6 % at 3.35 MeV assuming 40 % photo coverage of photomultipliers. We estimate that ZICOS experiment should be sensitive to the half life to be greater than 2 times 10^26 years, which corresponds to ⟨mν� � < 0.04 eV assuming gA = 1.25, gpp = 1.11 and QRPA model, if the radius of a detector is 3.0 m and the detector is filled with a liquid scintillator containing 10 wt.% concentration of a Zr(iprac)4 which includes 58.5% enriched Zr-96 isotope, and also we can reduce beta-gamma backgrounds emitted from Tl-208 to be one tenth order of magnitude of KamLAND-Zen. In order to reduce those backgrounds, we will use Cherenkov image. We have already measured Cherenkov light in our liquid scintillator, and we will be able to extract Cherenkov light using a timing information, even though low light yield (a few % of scintillation). A proto-type ZICOS detector with 30 cm radius will demonstrate an ability of the background reduction using Cherenkov image, and try to measure the limit of half-life for 96Zr neutrinoless double beta decay up to 10^23 years.   (09/06/2016)

	High power beam operation at J-PARC: status and future.			WG3-(oral)  accepted (WG3)
	The main ring (MR) of the Japan Proton Accelerator Research Complex (J-PARC) has been providing 30 GeV proton beams for particle and nuclear physics experiments since 2009. At present, high intensity beams of 2.2e14 protons per pulse (ppp) at beam power of 420kW with cycle time 2.48s are delivered to the neutrino oscillation experiment. The beam power has been steadily increased by 50% in last 2 years, following progression in beam tuning and hardware improvements. Main efforts in the beam tuning are to minimize beam losses and to localize the losses at collimator section. Recent improvements are corrections of resonances near operation setting of betatron tune, and adopting 2nd harmonic rf operation to reduce space charge effect with a larger bunching factor. Beam instabilities has been sufficiently suppressed with controlling chromaticity correction pattern and transverse feedback systems. The overview of recent progress in the beam tuning are presented. We plan to achieve the target beam power of 750 kW in 2018 by shortening the cycle time down to 1.3s. To achieve faster cycle, major upgrades of power supplies of main magnets, rf cavities, injection and extraction devices, and collimator capacity, are undergoing. We briefly report the status of these upgrades. Extensive beam studies to achieve the beam intensity beyond 2.2e14 ppp have been conducted with new betatron tune settings. Acceleration of two bunches holding 3.4e13 protons per bunch, which corresponds to 2.7e14 ppp with eight bunches, was successfully demonstrated. We present a new scenario toward the target beam power of 1.3 MW.   (09/06/2016)

	Direct measurements of dark particle candidates and the New Universe model			WG1-(poster)  refused ()
	With the help of our EQP based DWT model we have explored a new universe. The model operates with the SECP/SEMP particle objects. Such an object has a self-entangled component which beaves as dark particle, because only via gravity can interact with SM particles. They have no other direct interaction with the SM particles, but exists as each others self-entangled conjugated pair. It is interesting to identify these objects as targets of direct experimental investigations. Four cases are considerable for us. 1. The experimental studies of the 511 Kev intensive positron annihilation gamma radiation coming from the centers of galaxies, among them from our galaxy the Milky way (~1043 particles/s emission)are considerable phenomena. In the center of Milky Way a large antimatter cloud was identified with important positron and other components see Finkbeiner [2]. This we interpret as dark particle, dark electron components of SECP/SEMP objects coming through the d=0 surface via quantum fluctuation due to the extreme densities, energies, temperatures in super massive black hole centers. This way quantum tunneling produces this permanent and measurable effect. 2. The other case is exploration of neutral intermediate boson with ~17 MeV mass in the angular correlation measurements of 8Be nucleus deexcitation via internal pair conversion. In these pair conversion nuclear decay investigations at large angle correlations between the electron and positron an anomalous deviation has been found which could not be interpreted within the nuclear or standard particle model , Krasznahorkay [3]. We predict existence of similar objects in the low energy small scale non SM particle domain as components of our SECP/SEMP objects. We can identify it as scale boson or d<0 excitation of gamma, lepton, nucleon dark particles. We propose to investigate, clarify the role of the presence of the nucleus and shell via e+e- scattering, internal electron conversion studies, other nuclei, other deexcitations, etc. We predict to appear such intermediate dark particle peak at low energy and large e+ e- opening angles, which makes very interesting the experiment al results. 3. An interesting candidate can be the generated and experimentally investigated Majorana fermion excitation quasiparticles in solids as quantum spin liquid states recently published by Banerjee[4] which we can be identified as SECP/SEMP objects. As we propose d<0 components of SECP/SEMP objects can be the dark particles, also can be the antiparticles of the other d>0 component and this can be a direct investigation possibility. 4. It is already experimentally verified that neutrinos have non-vanishing small finite mass. Sterile neutrinos have been introduced to explain neutrino mass. Similar particle and dark neutrino in our SECP/SEMP model also occurs, so for us important are the results of continuous experiments to determine neutrino mass and mass generation mechanism, search for sterile neutrinos which are at the same time also dark particle candidates [5]. Further experiments and EQP/DWT theoretical studies can clarify if these objects really are dark particles and what types and characteristics they have. New analysis of existing experimental data and further experiments on binary systems and collisions of black holes, stars, galaxies, and also heavy ion reactions via QGP state formation e.g. Árvay et al. [6] can provide information about the new universe. Refs: [1] Z.

	After the measurement of the reactor mixing angle, there are two main unknowns in the three neutrino standard oscillation framework, namely the neutrino mass ordering and the establishment of CP violation in the neutrino sector. At the same time, Non-Standard neutrino interactions (NSI) provides a model independent Beyond the Standard Model scenario that can be probed in neutrino oscillations measured at different facilities. Along this talk I will introduce the NSI framework with some emphasis in the current NSI constraints and the NSI modifications to the Standard oscillation probabilities. After that I will give two examples of the NSI effects that can be tested at current reactors and accelerator-based facilities. Finally, I will comment on the NSI implications for the future neutrino program devoted to measure the mentioned unknowns.   (15/06/2016)

	The experiment to search for the muon to electron conversion at J-PARC MLF			WG4-(oral)  accepted (WG4)
	Muon to electron conversion ($¥mu$-$e$ conversion) is one of the charged lepton flavor violation (cLFV) processes, which is forbidden in the Standard Model of the particle physics (SM). However, theories beyond the SM predict the existence of the cLFV signature at the observable branching ratio. Therefore, the discovery of $¥mu$-$e$ conversion is a clear evidence of the new physics beyond the SM. DeeMe is an experiment to search for $¥mu$-$e$ conversion at J-PARC Material and Life Science Experimental Facility (MLF). DeeMe utilizes the 3-GeV 25-Hz pulsed proton beam from Rapid Cycling Synchrotron (RCS). The signal electrons from $¥mu$-$e$ conversion are produced in the muon production target and transported to the magnetic spectrometer by H Line. These electrons are directly emerged from the target with mono-energy and delayed timing, therefore they can be easily identified by momentum and time analysis. The single event sensitivities achieved by DeeMe for 1-year data acquisition are estimated to be $1 ¥times 10^{-13}$ and $2 ¥times 10^{-14}$ with graphite and Silicon-Carbide target. DeeMe is expected to improve the current limit by two orders of magnitude. The current upper limits of mu-e conversion are $4.3 ¥times 10^{-12}$ for Ti and $7 ¥times 10^{-13}$ for Au. DeeMe already has the Stage-2 approval from PAC under KEK-IMSS (Institute of Materials Structure Science), and we are aiming to start this experiment in 2016. In this talk, the recent status of DeeMe will be reported.   (15/06/2016)

	Kaon experiments at CERN: recent results and prospects			WG4-(oral)  accepted (WG4)
	In the first part of the talk, recent results from the NA48/2 and NA62 experiments at CERN are presented. After some highlights on the measurement of R_K, searches for lepton number violation and resonances in the K± → πμμ decays are reported; a new upper limit on the rate of the decay K± → π∓μ±μ± has been established, improving by more than an order of magnitude the limits set by previous measurements. Searches for two-body resonances in the K± → πμμ decays in the accessible range of masses and lifetimes are also presented. The second part of the talk is devoted to the present status of the search for K+ → π+ννbar at NA62. K+ → π+ννbar is one of the theoretically cleanest meson decay where to look for indirect effects of new physics, complementary to LHC searches. The NA62 experiment at CERN SPS is designed to measure the Branching Ratio of this decay with 10% precision. The performance of the sub-detectors of the experiment and the quality of the data collected in two pilot runs (2014 and 2015), acquired in view of the final measurement, are presented.   (20/06/2016)

It is a staged experiment designed to measure cross-section for interactions on argon that are important for the long-baseline neutrino physics and astrophysics program explored with deep underground detectors. The detector is a 5 ton liquid argon TPC placed in a portable and evacuable cryostat accompanied by a photon detection system for independent triggering. In the first stage, Mini-CAPTAIN (1 ton LAr prototype) was placed in the high energy neutron beam in February 2016, at the Los Alamos Neutron Science Center and is planned to take more data in September 2016. In the second phase, CAPTAIN will be placed in a lower energy neutrino beam to measure cross-sections at lower energy that are of interest for Supernova neutrino physics.

	Results of the Search for Sterile Neutrinos with IceCube			WG1-(oral)  accepted (WG1+WG5)
	The IceCube neutrino telescope at the South Pole has measured the atmospheric muon neutrino spectrum as a function of zenith angle and energy. Sterile neutrinos with eV-scale mass, as motivated by anomalies in short-baseline experiments, would be expected to cause significant changes in the $\bar{\nu_\mu}$ survival probability due to resonant, matter enhanced oscillations. For a 1 eV^2 sterile neutrino these effects would be strongest at energies around 3 TeV, where the statistics of the IceCube sample are high. This allows us to search for sterile neutrinos with small mixing angles in the mass range of interest. In this talk I will present the first results of this search.   (02/07/2016)

	T2K is a long-baseline neutrino oscillation experiment comprising of the J-PARC O(GeV) neutrino beamline, the ND280 near detector complex and a far detector (Super-Kamiokande) located 295 km away from J-PARC. In order to make precision measurements of neutrino oscillations a detailed understanding of both GeV-scale neutrino-nucleus scattering cross sec- tions and nuclear effects are essential. To achieve this, the latest CCQE-like analyses from the T2K near detectors utilise a wide variety of techniques including: water subtraction to obtain oxygen cross sections; joint neutrino/anti- neutrino fits and measurements of cross sec- tions in proton kinematics or composite proton-muon variables (such as transverse kinematic imbalance). Each of these new analyses will be presented, alongside current T2K CCQE-like results, with a view to demonstrating their potential to provide complementary precision cross-section measurements and innovative probes of nuclear effects.   (04/07/2016)

	Physics and Experimental Development towards IsoDAR@KamLAND			WG5-(oral)  accepted (WG3+WG5)
	The high endpoint nu-e-bar energy (~13 MeV) from the beta decay of Li-8 provides for a high-sensitivity Isotope Decay-At-Rest probe for sterile neutrinos in the (delta-m^2) ~ 1 to 10 eV^2 region. The First-generation IsoDAR experiment places a Li-8 source approximately 16 meters from the center of the 1 kton liquid scintillator KamLAND detector, providing the opportunity for observing few-meter wavelength oscillations directly in the fiducial volume of KamLAND. This experiment can also make precision electroweak measurements. A next-generation experiment can be constructed at a multi-kiloton site, such as JUNO. In order to produce the flux, Li-8 is generated primarily by neutron capture on Li-7. Neutrons are produced by a 10 mA, 60 MeV beam of protons striking a beryllium target. The proton beam is provided by a compact cyclotron that accelerates 5 mA of molecular H2+ ions. This talk addresses the physics opportunities and the recent results of our R&D program in a ddressing the technical challenges.   (14/07/2016)

	ICARUS			WG1-(oral)  poster (WG1)
	The ICARUS-T600 is the biggest LAr-TPC detector ever realized. The ICARUS Collaboration concluded a very successful, long duration run with the T600 detector at the LNGS underground laboratory, taking data both with the CNGS neutrino beam and with cosmic rays. It performed a sensitive search for anomalous nue appearance as suggested by LSND signal and experimental neutrino anomalies at reactors and with the calibration sources in solar neutrino searches. The analysis of the νμCC events collected with the CNGS beam is progressing, in view of the comparison with the expected flux in absence of anomalies. The collected cosmic ray triggers are being analyzed too aiming at studying the atmospheric neutrino interactions. The detector is being overhauled at CERN and will be ready to be installed at Fermilab by the end of this year to investigate within the SBN project the presence of sterile neutrino, exploring in three years of data taking the νμ to νe appearance signal with 5 sigma sensitivity in the parameter region indicated by the LSND experiment and measuring the νμ disappearance with a sensitivity exceeding an order of magnitude the present experimental limits.   (15/07/2016)

	Lepton production cross sections in quasielastic (anti)neutrino-nucleus scattering.			WG2-(poster)  accepted (WG2)
	Recently the measurements for theta13 have been made. Also in the experiments, a clear evidence for $\nu_\mu \leftrightarrow \nu_e$ or $\bar\nu_\mu \leftrightarrow \bar\nu_e$ oscillation signals have been seen. Now the emphasis is upon determining mass hierarchy in the neutrino sector as well as to find signals of CP violation in the leptonic sector besides measuring the parameters of PMNS matrix with high precision. For the determination of some of these parameters, accelerator experiments like T2K, MINERvA, MINOS, NOvA, etc. are taking data as well as experiments like MicroBooNE, DUNE, T2HK, etc. are planned. These experiments are in the (anti)neutrino energy region of a few GeV. In the energy region of < = 1GeV the major contribution to the event rates comes from the charged current quasielastic(CCQE) lepton production process followed by charged current induced one pion production process. We shall present the results of (anti)neutrino induced charged current quasielastic scattering cross sections from some nuclear targets in the energy region of Enu < = 1 GeV. The aim of the study is to confront electron and muon production cross sections relevant for $\nu_\mu \leftrightarrow \nu_e$ or $\bar\nu_\mu \leftrightarrow \bar\nu_e$ oscillation experiments. The effects due to lepton mass and its kinematic implications, second class currents and uncertainties in the axial and pseudoscalar form factors will be discussed for (anti)neutrino induced reaction cross sections on free nucleon as well as the nucleons bound in a nucleus where nuclear medium effects influence the cross section[1].

	Probing Nuclear Effects at the T2K Near Detector Using Transverse Kinematic Imbalance			WG2-(poster)  accepted (WG2)
	T2K is a long-baseline neutrino oscillation experiment comprising of the J-PARC neutrino beamline, the ND280 near detector complex and a far detector (SuperKamiokande) located 295 km away from J-PARC. In order to make precision measurements of neutrino oscillations, a detailed understanding of nuclear effects in neutrino scattering is essential. Nuclear effects are comprised of final state interactions (FSI) and initial state effects, including multi-nucleon interactions (such as 2p2h) and Fermi motion (FM). Recent studies have revealed that variables characterising kinematic imbalance in the plane transverse to an incoming neutrino beam can act as a unique probe of these nuclear effects. This work uses the T2K off-axis near detector (ND280) to measure the transverse distributions as an exclusive charged-current differential cross-section with no final state pions and at least one final state proton. The sensitivity of the measurement to nuclear effects (such as FSI strength and 2p2h normalisation) is critically analysed. These measurements will allow us to better understand the impact of nuclear effects on the observables in neutrino scattering, providing valuable constraints on the systematic uncertainties associated with neutrino oscillation measurements for both T2K and other accelerator-based neutrino experiments.   (15/07/2016)

	Constraint of the Charged Kaon Yield using $\nu_{\mu}$ Data in the NOνA Near Detector & Prediction of the $\nu_{e}$ Flux			WG1-(poster)  accepted (WG1)
	NOvA, a long-baseline neutrino oscillation experiment at Fermilab, is designed to measure $\nu_{e}$ appearance and $\nu_{\mu}$ disappearance rates in the NuMI beam. NOvA comprises two finely segmented liquid scintillator detectors at 14 mrad off-axis in the NuMI beam. Taking advantage of a tightly focused off-axis view of the NuMI neutrino beam, and a finely instrumented liquid scintillator detector, NOνA has an excellent opportunity to make high precision measurements of neutrino interactions using its Near Detector. An accurate prediction of the neutrino flux is needed for precision oscillation and cross-section measurements. In this poster, we will present Constraint of the Charged Kaon Yield using νμ Data in the NOνA near detector and the prediction of the νe Flux using NOvA near detector and external hadron-production experiment data.   (15/07/2016)

	High-Power Cyclotrons for Decay-At-Rest Neutrino Sources			WG3-(poster)  accepted (WG3)
	A program based on neutrinos from “Decay-At-Rest” sources has been under development for several years, based on a chain of innovative, high-current cyclotrons. DAEdALUS (using 800 MeV protons) is a CP violation study based on electron antineutrino appearance from a stopped pion source. IsoDAR (60 MeV protons, using a cyclotron whose design is suitable for the injector for the higher-energy DAEdALUS cyclotron) is a sterile neutrino search, based on beta decay of Li-8, by observing short-wavelength oscillations in a kiloton-scale liquid-scintillator such as KamLAND. These cyclotrons, which deliver 10 mA beams of protons on target, represent a new generation of high-current accelerators, whose applications can ultimately extend well beyond the neutrino field. Continuing R&D activities in ion-source development, efficient injection, and advanced simulation techniques for the highly-space-charge-dominated beams captured and accelerated in the cyclotrons will be discussed.   (21/07/2016)

	The NOvA experiment observes the oscillations that occur in a beam of muon neutrinos sent 810km from the source at Fermilab, IL to a 14kton detector in Ash River, MN.

The measurement of $\nu_\mu$ disappearance allows precise measurements of the oscillation parameters $\sin^2\theta_{23}$ and $\Delta m^2_{32}$; the search for Neutral Current disappearance could provide evidence of oscillations involving a new sterile state; and the measurement of $\nu_e$ appearance sheds light on the neutrino mass hierarchy and the CP-violating phase $\delta_{CP}$, and provides complementary information on $\sin^2\theta_{23}$   (23/07/2016)

	Some properties of lepton mixing and neutrino masses can be computed under the assumption of A5 and CP as a symmetry in the leptonic sector. The results show that four mixing patterns accommodate well the oscillation data, i.e. all the mixing angles are in the 3sigma confidence region.

	The Muon g-2 Experiment at Fermilab			WG4-(oral)  accepted (WG4)
	A new measurement of the anomalous magnetic moment of the muon, $a_\mu \equiv (g - 2)/2$, will be performed at the Fermi National Accelerator Laboratory with data taking beginning in 2017. The most recent measurement, performed at Brookhaven National Laboratory and completed in 2001, shows a 3.3-3.6 standard deviation discrepancy with the standard model value of g-2. The new measurement will accumulate 20 times those statistics using upgraded magnet, detector, and storage ring systems, enabling a measurement of g-2 to 140 ppb, a factor of 4 improvement in the uncertainty the previous measurement. This improvement in precision, combined with recent improvements in our understanding of the QCD contributions to the muon g-2, could provide a better than $5\sigma$ discrepancy from the standard model, a clear indication of new physics.   (23/07/2016)

	Complementarity Between Hyperkamiokande and DUNE			WG1-(oral)  accepted (WG1)
	In this talk we investigate the sensitivity to the neutrino mass hierarchy, the octant of the mixing angle $\theta_{23}$ and the CP phase $\dcp$ in the future long baseline experiments T2HK and DUNE as well as in the atmospheric neutrino observation at Hyperkamiokande (HK). These three experiments have the excellent facility to discover the above mentioned neutrino oscillation parameters in terms of both statistics and matter effect. In our analysis we find that the sensitivity is enhanced greatly if we combine these three experiments. Our results show that the hierarchy sensitivity of both T2HK and HK are limited due to the presence of parameter degeneracy. But this degeneracy is removed when T2HK and HK are added together. With T2HK+HK (DUNE), the neutrino mass hierarchy can be determined at least at $ 5 \sigma$ (8\,$\sigma$) C.L. for any value of true $\dcp$. With T2HK+HK+DUNE the significance of the mass hierarchy increases to almost 15 $\sigma$ for the unfavorable value of $\dcp$. For these combined setup, octant can be resolved except $43.5^\circ < \theta_{23} < 48^\circ$ at $5\sigma$ C.L for both the hierarchies irrespective of the value of $\dcp$. The significance of CP violation is around 10\,$\sigma$ C.L. for $\dcp\sim \pm 90^\circ$. Apart from that these combined facility has the capability to discover CP violation for at least $68\%$ fraction of the true $\dcp$ values at $5 \sigma$ for any value of true $\theta_{23}$. The precision by which a given $\dcp$ value can be measured is also excellent for this combined set up. We also find that, with combination of all these three, the precision of $\Delta m^2_{31}$ and $\sin^2\theta_{23}$ becomes 0.3\% and 2\% respectively.

	Isospin decomposition of the $\gamma^{(*)} N-->N^*$ transitions as input for constructing models of neutrino-induced reactions in the nucleon resonance region			WG2-(oral)  accepted (WG2)
	Constructing an accurate model for neutrino-induced reactions in the nucleon resonance region assumes more importance in making a precise interpretation of the detected data in the future neutrino-oscillation experiments. One of the major unknown parts of the neutrino-induced reactions in the nucleon resonance region is the matrix elements for the transition from the nucleon to a nucleon resonance induced by the weak current. However, the vector part of the weak-current matrix elements can be determined with the data of meson photo- and electro-production reactions off the nucleon, which are provided from the facilities such as ELSA, ELPH@Tohoku, JLab, MAMI, and SPring-8. In this talk, I will present our recent efforts to determine such vector-current matrix elements within a sophisticated coupled-channels framework.   (23/07/2016)

	It has been recently shown that in the presence of non-standard neutrino interaction with matter, even with an effective coupling as small as 0.01 times the Fermi constant, the proposed long baseline experiments may lose their ability to extract the yet-unknown neutrino parameters such as the Dirac CP-violating phase or the octant of $\theta_{23}$. We introduce models based on new $U(1)$ gauge symmetries with a sub-GeV gauge boson that give rise to both lepton flavor conserving and violating neutral current neutrino interaction with matter. We discuss various experimental constraints and suggest observations to test these models.   (23/07/2016)

	Leptonic CP Violation Predictions from Discrete Flavour Symmetry Approach			WG5-(oral)  accepted (WG5)
	Work done in collaboration with I. Girardi and S.T. Petcov In the reference 3-neutrino mixing scheme leptonic CP violation can be caused by the Dirac, $\delta$, and/or Majorana, $\alpha_{21}$ and $\alpha_{31}$, CP violation phases present in the unitary neutrino mixing matrix $U$. Using the fact that $U = U_e^\dagger U_\nu$, $U_e$ and $U_\nu$ being unitary matrices which diagonalise the charged lepton and neutrino mass matrices, respectively, we consider in a systematic way forms of $U_e$ and $U_\nu$ allowing us to derive sum rules for $\cos\delta$, $\alpha_{21}$ and $\alpha_{31}$, i.e., to express them in terms of the measured neutrino mixing angles present in $U$ and the angles (and phases in the case of sum rules for $\alpha_{21}$ and $\alpha_{31}$) contained in $U_{\nu}$, whose values are fixed by discrete flavour symmetry (generalised CP symmetry). We consider several concrete forms of $U_\nu$, including bimaximal, tri-bimaximal, golden ratio mixing forms. For each of these forms and forms of $U_e$ allowing to reproduce the measured values of the neutrino mixing angles, we obtain numerical predictions for $\delta$, $\alpha_{21}$ and $\alpha_{31}$. We then perform a statistical analysis of the predictions for $\delta$. Finally, using the obtained values of the CP violation phases, we present predictions for the effective Majorana mass in neutrinoless double beta decay. Our results, in particular, show that the measurement of $\delta$ along with improvement of the precision on the neutrino mixing angles can provide unique information as regards the possible existence of a new fundamental symmetry in the lepton sector.

It employs the most powerful proton accelerator of an ADS-like linac as the proton driver to produce a very intense and medium-energy neutrino beam mainly for the leptonic CP violation phase measurement. Another key property of the MOMENT scheme is the use of muon decays for the production of neutrinos in a long decay channel by superconducting solenoids. The talk overviews the recent progress of the project study, and also some relevant study such as the companion project – Experimental Muon Source at China Spallation Neutron Source.   (24/07/2016)

	ESSnuSB- The ESS neutrino facility for CP violation discovery			WG3-(oral)  accepted (WG3)
	The comparatively large value of the neutrino mixing angle $\theta_{13}$ measured in 2012 by neutrino reactor experiments has opened the possibility to observe for the first time CP violation in the leptonic sector. The measured value of $\theta_{13}$ also privileges the 2nd oscillation maximum for the discovery of CP violation instead of the usually used 1st oscillation maximum. The sensitivity at the 2nd oscillation maximum is about three times higher than at the 1st oscillation maximum implying a significantly lower sensitivity to systematic errors. Measuring at the 2nd oscillation maximum necessitates a very intense neutrino beam with the appropriate energy. The world’s most intense pulsed spallation neutron source, the European Spallation Source, has a proton linac with 5 MW power and 2 GeV energy. This linac also has the potential to become the proton driver of the world’s most intense neutrino beam with very high potential for the discovery of neutrino CP violation . The physics performance of that neutrino Super Beam in conjunction with a megaton Water Cherenkov neutrino detector installed ca 1000 m down in a mine at a distance of about 500 km from ESS has been evaluated. In addition, the use of such a detector will make it possible to extent the physics program to proton–decay, atmospheric neutrinos and astrophysics searches. The ESS proton linac upgrade, the accumulator ring needed for proton pulse compression, the target station optimization and the physics potential are described. In addition to the production of neutrinos, this facility will also be a copious source of muons which could be used to feed a low energy nuSTORM facility, a future neutrino factory or a muon collider. The ESS linac, under construction, will reach full operation at 5 MW by 2023 after which the upgrades for the neutrino facility could start. This project is now supported by the COST Action CA15139 "Combining forces for a novel European facility for neutrino-antineutrino symmetry-violation discovery" (EuroNuNet) as well as by EU Regional Structural Funds in the region in Sweden where the neutrino detector will be located.

RENO has made a definitive measurement of $\theta_{13}$ in 2012. Recently more precise measurements have been obtained and presented on the mixing angle and the reactor neutrino spectrum, using about 500 live days of data to observe an energy dependent disappearance of reactor $\overline{\nu_e}$ by comparison of prompt signal spectra measured in two identical near and far detectors. Furthermore, other recent results (5MeV excess, absolute flux measurements, n-H analysis, etc) will be shown. A large liquid scintillator and multi-purpose neutrino experiment, RENO-50, is proposed to be built for playing a leading role in neutrino physics and neutrino astronomy. The detector will be located at the underground of Mt. Guemseong in Naju, 50 km distant from the Hanbit nuclear power plant.

	Electric dipole moments of charged leptons with sterile fermions			WG5-(oral)  accepted (WG4+WG5)
	We address the impact of sterile fermions on charged lepton electric dipole moments. First, we consider a minimal extension of the Standard Model via the addition of sterile fermions which mix with active neutrinos. Our study reveals that, in order to have a non-vanishing contribution in this framework, the minimal extension necessitates the addition of at least 2 sterile fermion states to the Standard Model field content. Our conclusion is that sterile neutrinos can give significant contributions to the charged lepton electric dipole moments, some of them lying within present and future experimental sensitivity if the masses of the non-degenerate sterile states are both above the electroweak scale. The Majorana nature of neutrinos is also important in order to allow for significative contributions to the charged lepton electric dipole moments. Second, we apply this computation for electric dipole moments for the Inverse Seesaw model as an specific model. In this case, the two pairs of (heavy) pseudo-Dirac mass eigenstates can give significant contributions to the electron electric dipole moment, lying close to future experimental sensitivity if their masses are above the electroweak scale. The major contribution comes from two-loop diagrams with pseudo-Dirac neutrino states running in the loops. In our analysis we further discuss the possibility of having a successful leptogenesis in this framework, compatible with a large electron electric dipole moment.   (25/07/2016)

	Bright muon sources offer the potential to study neutrinos, the Higgs boson, and search for new physics at the energy frontier. The Muon Accelerator Program (MAP) in the United States began in 2010, with the goal of proving the feasibility of building such a machine. MAP's efforts are nearing completion, and a great deal of progress has been made on each of the accelerator's subsystems. A Higgs factory allows for s-channel production of the Higgs, amounting to ~13,500 Higgs produced per $10^7$ seconds, while providing a beam energy spread on the order of 0.004\% with which to measure the Higgs width. A Higgs factory relies on a high power proton driver and suitable target, significant six dimensional cooling, and moderate reacceleration. The foreseen requirements and current status for each of these systems will be outlined.   (26/07/2016)

	On neutrinoless double beta decay in the nuMSM			WG5-(oral)  accepted (WG5)
	We consider the Standard Model (SM) extended by three right-handed neutrinos with the masses below the electro-weak scale, which is called the nuMSM. The seesaw mechanism for the tiny active neutrino masses works even in this case by taking the very suppressed neutrino Yukawa couplings. In this model the dark matter can be the lightest right-handed neutrino and the baryon asymmetry of the universe can be explained by other two heavier right-handed neutrinos by invoking the mechanism via neutrino oscillations. We examine the neutrino less double beta decay in the nuMSM. We show analytically that the effective mass of the neutrino less double beta decay can exceeds the SM prediction without loss of the successful baryogenesis. Especially, we show that the effective mass can be three times larger than the SM prediction when the active neutrino masses follow the inverted hierarchy.   (26/07/2016)

	Conversions of Bound Muons: LFV from Doubly Charged Scalars			WG4-(oral)  accepted (WG4+WG5)
	Apart from naturally explaining their smallness, models in which neutrino masses are generated only at the loop level are particularly interesting as they often contain electrically charged scalar fields. These additional particles contribute in particular to lepton flavour and/or number violating processes, like mu -> e gamma or neutrinoless double beta decay. On the other hand, at LHC new charged scalars could be identified from several decay and production channels, generating complementarity with low energy experiments. Using a radiative model based on an effective vertex as example, we discuss a setting involving a doubly charged scalar particle. However, our results even hold for much more general settings involving such a particle. We focus on a certain lepton flavour violating process, namely mu-e conversion in muonic atoms. This process is particularly interesting since future experiments will improve the bounds on the branching ratio by several orders of magnitude and thus will lead to strong constraints on the model space which could even challenge current LHC bounds. As this framework could stem from several known UV completions, our results are in fact rather general.   (26/07/2016)

	Sterile Neutrino Dark Matter Production from Scalar Decay			WG5-(oral)  accepted (WG5)
	Sterile neutrinos with a mass in the keV range form a good candidate for dark matter. They are naturally produced from neutrino oscillations via their mixing with the active neutrinos. However the production via non-resonant neutrino oscillations has recently been ruled out. Sterile neutrino dark matter production from scalar decay is an attractive possibility to circumvent astrophysical constraints. I will discuss sterile neutrino DM production from scalar decay and its implications for small-scale structure. In particular I will focus on the neutrinophillic two Higgs doublet model, where neutrino mass is generated via the radiative seesaw or the usual seesaw mechanism with an additional suppression from a vev seesaw.   (26/07/2016)

	We derive constraints on the mixing of heavy Seesaw neutrinos with the SM fields. We explore and compare both a completely general scenario where the heavy neutrinos are integrated out and the more constrained case of only 3 extra heavy states. The latter assumption implies non-trivial correlations that do not allow to saturate all model-independent bounds. Among the electroweak and flavor observables included in the global fit, $\mu\Rightarrow e\gamma$ sets the present strongest bound on the additional neutrino mixing, while in the future it will be dominated by $\mu-e$ conversion in nuclei. Increasing its sensitivity in future experiments could probe non-unitarity in lepton-flavor-violating processes.   (26/07/2016)

J-PARC is a multi-purpose facility where the variety of secondary-particle beams are produced and are used in a wide range of scientific fields, such as fundamental nuclear and particle physics, materials and life science, and nuclear technology. Neutron, pion, muon, kaon and neutrino beams are produced through collisions between the high-power proton beams and target materials. Requirement to increase the intensity of the proton beam is getting higher and higher for further advanced researches. Consequently, the thermal load and the irradiation effect to the target materials are also getting severer. Simultaneously, cooling methods to remove the thermal load are restricted by requirements from physics experiment. In addition, these targets must be handled by remote handling, since they are highly activated. So, each target is designed considering the individual conditions. Present status of the high-power target operation at J-PARC will be described in this presentation.   (26/07/2016)

	Status of J-PARC neutrino beamline operation and future upgrade plan			WG3-(oral)  accepted (WG3)
	J-PARC neutrino beam-line produces a high intensity muon neutrino beam using 30 GeV protons from the J-PARC Main Ring (MR) accelerator. This neutrino beam is used for T2K long base-line neutrino oscillation experiments as well as other test experiments at the neutrino facility. The current beam power is ~400kW while it is still being increased. Further beam power improvement is planned with upgrading MR magnet power supply, RF systems and collimators. The upgrade of MR magnet power supply is planned in 2018 and the beam power after the upgrade will be increased to the design power of 750kW and beyond, to 1.3 MW. Upgrade of the neutrino beam-line such as the proton beam monitors, DAQ/control system, horns and radioactive material handling, is also planned. In this talk, status of J-PARC neutrino beam-line operation and future upgrade plan will be presented.   (27/07/2016)

	Impact of systematic uncertainties on neutrino oscillation analysis			WG2-(oral)  accepted (WG1+WG2)
	Modern experiments aimed at measuring neutrino oscillation parameters have entered the age of precision. The determination of these parameters strongly depends on the ability to reconstruct the energy distributions of neutrino beams. I discuss two different energy reconstruction techniques: the reconstruction based on the kinematic of the outgoing lepton and the one based on the calorimetric method, including realistic detector capabilities. Furthermore, I will also present the results of a study aimed at quantify how the oscillation analysis is affected by the uncertainties associated with the description of the neutrino-nucleus cross section in the 2p2h sector.   (28/07/2016)

	MINERvA cross-sections			WG2-(oral)  accepted (WG2)
	MINERvA is a dedicated neutrino-nucleus scattering experiment sited in the NuMI neutrino beam Fermilab. MINERvA collected data in the NuMI low-energy configuration and more recently in a higher energy configuration. Using existing hadron production data, MINERvA has reevaluated the neutrino flux and its uncertainties yielding the smallest flux uncertainties in a multi-GeV broad-band beam. This flux was crosschecked using both neutrino atomic electron scattering and the low recoil flux method. Using these updated fluxes we have studied the QE-like channel and nuclear effects, which are compared to theories and show clear evidence of nuclear effects. MINERvA results on pion production, inclusive, and DIS results will be covered in Dr. Morfin's talk.   (28/07/2016)

	Quasielastic production of hyperons			WG2-(oral)  accepted (WG2)
	We shall discuss $\overline{\nu_l}$ induced quasielastic charged current hyperon production from nucleons and nuclei. The inputs are nucleon-hyperon transition form factors determined from experimental data on quasielastic ($\Delta S = 0$) charged current (anti)neutrino–nucleon scattering and the semileptonic decay of neutron and hyperons assuming G–invariance, T–invariance and SU(3) symmetry. These processes are generally Cabibbo suppressed as compared to the $\Delta$ production process but could be important in the low energy region($\leq 1GeV$ ) of antineutrinos relevant to MicroBooNE, T2K and atmospheric antineutrino experiments. The results would be presented for the total scattering cross section $\sigma$, $Q^2$ distribution, etc. for $\overline{\nu_l}$ scattering off nucleon and nucleons bound in $^{12}C$, $^{40}Ar$, $^{56}Fe$ and $^{208}Pb$ nuclear targets, where a single hyperon is produced. The calculations are done using the local density approximation. The nuclear medium effects due to the Fermi motion and Pauli blocking, and the final state interaction effects due to hyperon–nucleon scattering have been taken into account. The hyperon produced inside the nuclei decay to pion and nucleon, and the decay width of pionic decay modes of hyperons is highly suppressed in the nuclear medium, making them live long enough to pass through the nucleus and decay outside the nuclear medium and thus less affected by the strong interaction of nuclear field. The pions arising due to hyperons, are compared with the pions being produced through the $\Delta$ production where due to the effect of Pauli blocking, Fermi motion of the nucleon, renormalization of $\Delta$ properties in the nuclear medium and the FSI of pions with the residual nucleus, the cross sections are reduced by more than 25\% than the pions produced from $\Delta$ off free nucleon target at low energies. Therefore, for $E_{\overline{\nu_l}} \leq 1GeV$ energy region the pions produced from hyperons become compatible with the pions produced from the $\Delta$. The results would be presented for $Q^2$-distribution, lepton energy distribution and the total cross sections. We shall also discuss the longitudinal ($P_L(Q^2)$) and perpendicular ($P_P (Q^2)$) polarizations of final hyperon($\Lambda,\Sigma$) produced in the antineutrino induced quasielas- tic charged current reactions on nucleon targets. The sensitivity of axial dipole mass $M_A$, pseudoscalar form factor, neutron electric form factor, etc. on $P_L(Q^2)$ and $P_P (Q^2)$ would be discussed. We have compared the theoretical results with the available experimental results from CERN. Predictions for the flux aver- aged cross sections and polarization components have been made for the future experiments being done with antineutrino beams at T2K, MicroBooNE and MINER$\nu$A.   (28/07/2016)

	Nuclear medium effects in the deep inelastic charged lepton/neutrino-A scattering			WG2-(oral)  accepted (WG2)
	Deep Inelastic Scattering(DIS) experiments using charged lepton/neutrino as probe have been important tool to explore the partonic structure of nucleons and nuclei. Recently the importance of nuclear medium effects in the DIS region has been emphasized by several authors. In this talk, we shall discuss the effect of nuclear medium on electromagnetic $F^{EM}_{iA} (x,Q^2),\ i = 1 − 2 (A = nucleus)$ and weak $F^{Weak}_{jA} (x,Q^2), j = 1 − 3$, structure functions for a wide range of $x$ and $Q^2$ using a microscopic nuclear model which takes into account the effects of Fermi motion, nuclear binding and nucleon correlations through a relativistic nucleon spectral function. The contributions of $\pi$ and $\rho$ mesons as well as shadowing effects are also included. The details are given in Refs.[1-2]. We shall present a comparison of $F_{1A}(x,Q^2)$ with $F_{2A}(x,Q^2)$ structure functions in several nuclei like carbon, argon, iron and lead, and to study the violation of Callan-Gross relation in nuclei. We shall compare these results with recent data of JLab [3]. A quantitative estimate of the nuclear medium effects in $F^{EM}_{iA} (x,Q^2), i = 1 − 2 (A = nucleus)$ and $F^{Weak}_{jA} (x,Q^2), j = 1 − 3$, will be presented. Using these nuclear structure functions discussed above, we shall present the results for differential scattering cross sections in various nuclear targets such as carbon, argon, iron and lead, and compare them with the recent data available from MINER$\nu$A experiment for $\frac{\sigma^A}{\sigma^{CH}$ (A= C, Fe, Pb) [4]. Presently parity vioalting asmmetry($A_{PV}$) in the DIS of polarized electron beam from deuteron has been measured at JLab and there exist future plans to measure this assymmetry from nuclear targets. We shall present the results for $A_{PV}$ in several nuclear targets. This study may provide the information about weak electron and quark couplings to the Z boson as well as the (anti)quark parton distributions in nucleons and thier modification in nuclei due to nuclear medium effects.\\ \bf{Bibliography} 1.

	First Double-Detector Results from the Double Chooz Experiment			WG1-(oral)  accepted (WG1)
	Double Chooz is a reactor neutrino experiment aiming to measure the neutrino mixing angle $\theta_{13}$. The first non-zero indication of $\theta_{13}$ from a reactor experiment was provided by Double Chooz in 2011. A robust observation of $\theta_{13}$ was followed in 2012 by the Daya Bay and RENO experiments with multiple detectors. The final precision of $\theta_{13}$ by reactor experiment is of critical importance for current and future experiments to address the possible observation of CP violation in the neutrino sector. Systematic errors in reactor experiments are reaching the per-mill level, therefore, comparison of measurements from different experiments is crucial. In addition to the Far detector, the Near detector started operation since December 2014, which allows us to significantly improve the sensitivity of $\theta_{13}$. In this talk, we will show the first double-detector results for $\theta_{13}$, combining ~1 year of double-detector and ~2 years of single-detector data analysis.   (29/07/2016)

	Accelerator developments for SHiP and FCC			WG3-(oral)  accepted (WG3+WG5)
	The CERN SPS fixed target progamme in the so-called North Area uses a third order slow extraction to extract a 400 GeV proton beam onto experimental targets in a few seconds. The proposed SHiP experiment (Search for Hidden Particles) will demand record numbers of slow-extracted protons for fixed target physics at 400 GeV. Without improvement of the extraction efficiency this would induce hihger levels of activation making hands-on maintenance of the extraction hardware prohibitive. The main challenges and developments towards these improvements are presented. For the further future (physics data could possibly start in ~2035) a Future Circular Collider is under study. This is based on a 100 km pp-collider at 100 TeV centre of mass, which might be preceded by a 100 km e+e--collider. This study, and in particular the high energy proton booster ring needed for it, may also provide an interesting opportunity for fixed target experiments at roughly 1.5-3.3 TeV proton energy. The physics challenges for such a project are outlined together with some of the possible future developments that could ensure the slow extraction of such a beam onto a target.   (29/07/2016)

	Status and future prospects for charged Lepton flavor violation searches at B factories and Belle-II			WG3-(oral)  accepted (WG3+WG4)
	Lepton Flavor Violating (LFV) tau decays are strongly suppressed in the Standard Model while some of New Physics models indicates the branching fractions of several tau LFV decay modes are observable in the B factory experiments. Belle has studied 48 LVF tau decay modes and set 90% C.L. upper limits on the branching fractions, which are several orders of magnitude larger than the prediction. And then the experiment is in an upgrade to increase statistics of the data sample by a factor of 50. In this presentation, we review the current tau LFV studies and discuss future prospects in the Belle II experiment.   (31/07/2016)

	Ionization cooling demonstration			WG3-(oral)  accepted (WG3)
	Muon beams of low emittance provide the basis for a detailed study of the neutrino avour physics at a Neutrino Factory and for lepton- antilepton collisions at energies of up to several TeV at a Muon Collider. Ionization cooling provides the only practical solution for reduction of the muon beam emittance, because it is fast enough to cool the beam within the short muon lifetime. The emittance reduction is achieved by passing the muons through a low-Z material (absorber), in which they lose energy via ionization, reducing both their longitudinal and transverse mo- mentum. The longitudinal component is restored by accelerating cavities, providing a net reduction of the beam emittance. The international Muon Ionization Cooling Experiment (MICE) aims to build a section of a cool- ing channel that can demonstrate the principle of ionization cooling. A major revision of the scope of the project was carried out over the summer of 2014. The revised project plan will be described and the capability of delivering a demonstration of ionization cooling will be discussed   (01/08/2016)

	Neutrino oscillations with a non-unitary lepton mixing matrix			WG5-(poster)  accepted (WG5)
	The see-saw mechanism, which explains the smallness of the active neutrino masses, also implies a non-unitary lepton mixing matrix. The deviation from unitarity is negligible in this high scale see-saw models. However, in the low scale see-saw models a 'large' unitarity deviation is allowed. By assuming a 'model independent' approach, we study the phenomenological implications of having a non-unitary lepton mixing matrix with potential of being observed at long baseline neutrino oscillation experiments. first, a very convenient formalism, to describe neutrino oscillations in this context, will be introduced. Finally, we will highlight the parameter degeneracies, coming from the non-unitarity, in the (anti)neutrino (dis)appearance channel.   (01/08/2016)

	Multiple Coulomb Scattering Measurements of Muons in MICE			WG3-(oral)  accepted (WG3)
	Multiple coulomb scattering is a well known electromagnetic phenomenon experienced by charged particles traversing materials. However, from recent measurements by the MuScat experiment it is known that the available simulation codes, specifically GEANT4, overestimate the scattering of muons in low Z materials. This is of particular interest to the Muon Ionization Cooling Experiment (MICE) which has the goal of measuring the reduction of a muon beam emittance induced by energy loss in low Z absorbers. Multiple scattering induces positive changes in the emittance in contrast to the reduction due to ionization energy loss. It therefore is essential that MICE measures multiple scattering for its absorber materials; lithium hydride and liquid hydrogen; and validate the multiple scattering against known simulations. MICE took data with magnetic fields off suitable for multiple scattering measurements in the spring of 2016. The results of these measurements and comparison of the da ta to available simulations will be discussed. Further measurements of multiple scattering with magnetic fields on are planned and the impact of the increased angular acceptance on the resulting measurements will also be discussed.   (02/08/2016)

	Testable Baryogenesis in Seesaw Models			WG5-(poster)  accepted (WG5)
	We revisit the production of baryon asymmetries in the minimal type I seesaw model with heavy Majorana singlets in the GeV range. In particular we include for the first time "washout" effects from scattering processes with gauge bosons and higgs decays and inverse decays, besides the dominant top scatterings. We show that in the minimal model with two singlets, and for an inverted light neutrino ordering, future measurements from SHiP and neutrinoless double beta decay could in principle provide sufficient information to predict the matter-antimatter asymmetry in the universe up to a sign. We also show that SHiP measurements could provide very valuable information on the PMNS CP phases.   (02/08/2016)

	Measurement of emittance			WG3-(oral)  accepted (WG3)
	The Muon Ionization Cooling Experiment (MICE) collaboration will demonstrate the feasibility of ionization cooling, the technique by which it is proposed to cool the moun beam at a future neutrino factory or muon collider. The muon beam emittance is measured on a particle-by-particle basis. Measurements are made before and after the cooling cell using a high precision scintillating-fibre tracker in a solenoidal field. A pure muon beam is selected using a particle identification system that can reject efficiently both pions and electrons. The emittance of the MICE muon beam has been measured for the first time using the scintillating-fibre tracking system. The two spectrometers were powered together with the focus coil module in July 2016 and muons tracks were measured up and downstream the cooling cell. The performance of the tracking and the analysis techniques required for this precision measurement are shown. Also presented is the expected emittance change to be observed for different lattices used in the ongoing MICE Step IV.   (04/08/2016)

	The Accelerator Neutrino Neutron Interaction Experiment (ANNIE) at Fermilab			WG2-(oral)  accepted (WG2)
	ANNIE is specifically designed to perform a measurement of the final-state neutron abundance in high-energy neutrino-nucleon interactions as a function of momentum transfer.  The experiment uses the Booster Neutrino Beam (BNB) at Fermilab, which provides a controlled beam of dominantly muon neutrinos with a peak energy of 0.7 GeV and a spectrum similar to that of atmospheric neutrinos.   The two key components for studying neutrino-nucleon interactions are a volume filled with 23 tons of Gadolinium-doped water giving a high neutron detection efficiency, and the first use of Large Area Picosecond Photodetectors (LAPPDs) giving unprecedented track reconstruction accuracy in a water Cherenkov detector. A better understanding of the neutron multiplicity in neutrino-nucleon interactions is critical for reducing the systematic uncertainties in precision neutrino oscillation measurements arising from nuclear effects.  The measurements will also help to understand the application of neutron tagging to reduce backgrounds from atmospheric neutrinos, which is important for improving the sensitivity of  future proton decay experiments, and for achieving a better flux sensitivity for detecting the diffuse supernova neutrino background.  Finally, the demonstration of LAPPDs in a physics measurement could prove groundbreaking for future water Cherenkov detectors.  A status report of ANNIE will be provided, including the construction and experience from first data taking in summer of 2016. An outlook for the next phases of the physics measurements will be given.   (04/08/2016)

	MuCool Test Area Experimental Program Summary			WG3-(oral)  accepted (WG3)
	Muons have a potential of producing well-characterized neutrino beams for precise, high sensitivity studies as well as being a candidate particles for collider reaching multi-TeV energies. To efficiently cool the muon beam, some designs require high gradient operation of RF cavities in strong external solenoidal focusing magnetic field. It was experimentally shown that the problem of RF breakdown is aggravated if external magnetic field is applied.  The MuCool Test Area (MTA) is a unique accelerator R&D facility, built specifically to test RF components for a muon ionization cooling channel in external multi-Tesla solenoidal field with and without the presence of a beam.  As a part of MTA experimental program, high-gradient performance of 805 and 201MHz cavities as well as dielectric loaded high-pressure 805MHz cavities was tested. This talk will cover a review of MTA experimental program and will discuss the most interesting and promising results.   (20/08/2016)

	BabyMIND: A magnetised spectrometer for the WAGASCI experiment			WG2-(poster)  accepted (WG2)
	The BabyMIND detector is a prototype of a Magnetised Iron Neutrino Detector (MIND) for a neutrino factory, and will serve as a spectrometer to identify muon charge in the WAGASCI neutrino cross-section experiment being built at JPARC. This 50 ton spectrometer is being built at CERN and consists of 33 magnetised iron planes and 14 scintillating detector modules, consisting of vertical and horizontal extruded scintillator planes with wavelength shifting fibres read out by Hamamatsu Multi-pixel Photon Counters (MPPC). It is able to reconstruct muons with > 95% efficiency and determine the muon charge with >90% in a muon momentum range between 0.2 and 6 GeV/c. The BabyMIND detector is currently under construction, with an expected completion of April 2017. A comprehensive test beam was carried out at CERN between June and July 2016 to determine the performance and characteristics of the electronics readout. In this poster, we will present muon reconstruction results from the test beam and we will show the expected final performance of the BabyMIND spectrometer. Note: apologies that this is submitted late, since we did not have the results presented in this poster until last week.
