Recent Results From The Daya Bay Reactor Antineutrino Experiment

• Christopher White (IIT)

Room: Refectory The Daya Bay experiment is designed to provide a precise measurement of the smallest neutrino-mixing angle, θ13. It is located at the Daya Bay Nuclear Power Complex in southern China. Eight antineutrino detectors with identical design, each with a 20-t target, are deployed in three underground experimental halls at different distances from three clusters of nuclear reactors for detecting the low-energy electron antineutrinos emitted from the cores. A value of sin22θ13 is determined by comparing the observed rate of antineutrinos in the far detectors with the predicted one based on the measured rates obtained from the near detectors. This kind of relative measurement can reduce the systematic uncertainties significantly. Using this approach, Daya Bay reported the discovery of a non-zero value for sin2θ13 with a statistical significance of more than five standard deviations in March 2012. The recent results and prospects of Daya Bay will be presented in this talk.

Long Baseline Experiments in Japan

• Masashi Yokoyama (University of Tokyo)

Room: Refectory In this talk, the past, present and future of long baseline experiments in Japan will be reviewed. T2K has recently reported an evidence for electron neutrino appearance from muon neutrino beam, which together with reactor experiments established non-zero value of theta_13. This opened a possibility of studying neutrino CP asymmetry and mass hierarchy in future experiments. I will discuss what has been achieved by T2K so far, what can be achieved with T2K in future (with possible anti-neutrino mode running), and prospects of Hyper-Kamiokande, a 1Mton water Cherenkov detector proposed in Japan.

Phenomenology of neutrino oscillations

• Silvia Pascoli (University of Durham (GB))

Room: Refectory In recent years, neutrino experiments have achieved a remarkable precision in the measurements of the oscillation parameters. I will review the current knowledge, including possible hints of sterile neutrinos, and I will discuss the experimental strategies for the determination of the mass hierarchy, the existence of leptonic CP-violation and the tests of the standard three neutrino mixing scenario, which remain open questions. In particular, I will focus on the phenomenology of long baseline and short baseline neutrino oscillations.

Next Questions In Neutrino Physics with the NOvA and LBNE Experiments

• Mark Messier (Indiana University)

Room: Refectory The discovery of neutrino mass in 1998 opened a new window of particle physics for exploration. Since then, we have learned much of this new landscape. We have learned that neutrinos are very light and that they mix in large combinations, unlike quarks which mixing only slightly, and we have, in some cases, precise, measurements of these mixings. Many questions, however, remain. Fermilab is embarking on a long term program to fully explore these remaining questions. The next major step will come from the NOvA experiment which will use beams of both muon neutrinos and muon antineutrinos and measure the rate of disappearance of these neutrinos from the beam as well as their oscillation probabilities to electron-type neutrinos. From these observations NOvA will probe unanswered questions of the neutrino mass hierarchy and the symmetries of the neutrino mixing, as well as make tests of the standard framework used to understand neutrino oscillations. Construction of the experiment is well underway and first data will begin when operation of the Fermilab accelerators resumes in June of this year. Beyond NOvA, planning for the next experiment, LBNE is underway. LBNE will expand the physics program started by NOvA by lengthening the neutrino flight distance to 1300 km and studying the oscillation probabilities over a wide range of energies. With a large detector located underground LBNE will target discovery of CP violation in neutrinos while also probing physics at the GUT scale through study of proton decay.

LAGUNA and LBNO: Towards the next generation neutrino observatory in Europe

• Thomas Patzak (A)

Room: Refectory I'll describe the LBNO strategy to address mass hierarchy and CP phase measurements as well as the astro particle and nucleon decay. This strategy is the outcome of the European design studies LAGUNA and LAGUNA-LBNO. The LBNO approach is based on a staged experiment using a conventional beam and a LAr detector in double phase operation together with a magnetized iron detector at very long baseline of 2300 km and deep underground in its first stage. The new facility is a unique tool to measure mass hierarchy at the 5 sigma level over the whole phase space, independent of the theta 23 octant. The LBNO experiment can be scaled and adapted to the need physics tells us. The baseline of 2300km is perfect for the neutrino factory.

Neutrinos from stored muons: the nuSTORM facility

• Kenneth Long (Imperial College London)

Room: Refectory The nuSTORM facility will provide electron- and muon-neutrino beams from the decay of 3.8GeV muons confined within a storage ring.  The instrumentation of the ring, combined with the excellent knowledge of muon decay, will make it possible to determine the neutrino flux at the %-level or better.  The neutrino and anti-neutrino event rates are such that the nuSTORM facility serving a suite of near detectors will be able to measure \nu_eN and \nu_\muN cross sections with the %-level precision required to allow the next generation of long-baseline neutrino-oscillation experiments to fulfil their potential.  A detector placed approximately 1500m from the end of the decay straight, combined with a near detector, can be used to make exquisitely sensitive searches for sterile neutrinos.  The status of the nuSTORM project will be presented along with the performance of the facility in terms of sterile-neutrino sensitivity and precision on measurements of neutrino-nucleus scattering.

Neutrino cosmology after Planck

• Steen Hannestad (Aarhus University)

Room: Refectory Cosmology is becoming an increasingly powerful laboratory for neutrino physics, with current observations providing stringent bounds on parameters such as the absolute neutrino mass and the cosmological neutrino energy density. I will review the status of the field, and present new results, including an analysis of the Planck CMB measurements. I will also discuss the future of the field, in particular the importance of the upcoming ESA satellite mission EUCLID for neutrino cosmology.

Recent results from the OPERA experiment

• Yuri Gornushkin (Joint Inst. for Nuclear Research (RU))

Room: Refectory The OPERA experiment is aiming at observation of the nu-mu to nu-tau oscillations in  appearance mode through a direct registration  of tau leptons in nu-tau CC interactions in the detector. Neutrinos from CERN are registered in the hybrid detector which is located at the LNGS underground laboratory in Italy 730 km away. The data taken in 2008-2012 are being analysed and so far 3 nu-tau candidate events are already discovered. Given a very low background level,   a significance of the observation is about 3.5 sigmas. The OPERA is also sensitive to a subdominant nu-mu to nu-e oscillations. Recently new results on the nu-e registration in OPERA were obtained providing further restriction on non-standard neutrino oscillations.

Perspectives for the measurement of mass hierarchy with the Daya Bay II experiment

• Changgen Yang (IHEP, Beijing)

Room: Refectory Neutrino physics is the frontier of particle physics, astrophysics and cosmology. Neutrino mixing is the only phenomena beyond the Standard Model. The large and precise measurement of q13 mixing angle of Daya Bay experiment opened an era for many other neutrino precise measurements. The goal of Daya Bay II experiment is going to measure the neutrino mass hierarchy with a baseline of 60 km from reactor cores. The challenge of Daya Bay II experiment, the concepts design of detectors, site, cost and schedule will be shown.

Determination of the neutrino mass hierarchy with underwater and ice neutrino telescopes

• Christian Spiering (DESY)

Room: Refectory The talk will focus on status and prospects of PINGU, the conceived very dense inner part of IceCube, which aims determining the mass hierarchy with the help of atmospheric neutrinos. It will also address a very recent idea of Jurgen Brunner (Marseille) who proposes to direct a beam from Protvino to ORCA, a very dense detector at the present ANTARES

Ultrahigh energy neutrinos at the Pierre Auger Observatory

• Jan Ebr (Institute of Physics, Prague)

Room: Refectory The Pierre Auger Observatory is the largest cosmic ray observatory in operation. It consists of the surface array, which detects secondary particles at ground level using water-Cherenkov tanks, and 27 fluorescence telescopes. Even though it was designed for cosmic ray physics, it is also sensitive to neutrinos of all flavors above 0.1 EeV. Neutrinos can produce observable air showers when they interact in the atmosphere or in the Earth's crust (in the case of tau neutrinos). With the surface array we can see these showers as very inclined showers produced close to the ground. These can be distinguished from showers initiated by cosmic rays using the time structure of signals in the water-Cherenkov tanks. No neutrino candidates have been found, which allows us to place competitive limits to the diffuse flux of neutrinos in the EeV range and above as well as limits on the flux from point-like sources.

Detector DANSS and the problem of sterile neutrinos

• Alexander Olshevskiy (Joint Inst. for Nuclear Research (RU))

Room: Refectory Detector DANSS is constructed at the Kalinin Power Plant in Russia to monitor the flux of anti-neutrino from the reactor. Being installed at a small distance from the core it will allow at the same time to measure possible short distant oscillations of anti-neutrino into sterile states. First results with a reduced  version of detector were obtained recently.

Neutrino mass measurement with the KATRIN experiment

• Ferenc Glueck (KIT, Karlsruhe)

Room: Refectory The aim of the KArlsruhe TRItium Neutrino experiment KATRIN is the direct and model independent determination of the absolute neutrino mass scale down to 0.2 eV. For this purpose, the integral electron energy spectrum will be measured close to the endpoint of molecular tritium beta decay. The electrostatic retardation method with magnetic adiabatic collimation (MAC-E filter) combines high energy resolution with high statistics and small background. The various components of the experiment (gaseous tritium source, pumping-transport system, pre- and main spectrometer, detector and rear system) will be reviewed, together with various systematic effect and background issues. In addition, possibilities for light and keV sterile neutrino detections will also be discussed.

Searching for Neutrinoloess Double Beta Decay with NEMO-3 and SuperNEMO

• Stefan Soldner-Rembold (University of Manchester (GB))

Room: Refectory The observation of neutrinoless double beta decay will confirm the Majorana nature of neutrinos and it will provide first evidence of lepton number violation. The NEMO-3 experiment took data from 2003 to 2011, with Mo-100 and Se-82 as main sources. The SuperNEMO experiment improves on the NEMO-3 technique by increasing the mass of the source, improving the energy resolution and the detector efficiency, and by reducing backgrounds. The SuperNEMO experiment, using a tracker-calorimeter technique, will be able to measure the full kinematic signature of the decays, which is an important condition for studying the underlying physics mechanism of neutrinoless double beta decay. The SuperNEMO demonstrator module is currently under construction, with data taking due to begin next year. The latest results from NEMO-3 will be summarised, and the current status of the SuperNEMO experiment will be presented.

• Michal Malinský (Charles University, Prague)
