Description

The fifth Annual Large Hadron Collider Physics conference was held in Shanghai and hosted by Shanghai Jiao Tong University on May 15-20, 2017.

The LHCP conference series was initiated in 2013 by merging two international conferences, Physics at Large Hadron Collider Conference and Hadron Collider Physics Symposium. The program will be devoted to a detailed review of the latest experimental and theoretical results on collider physics, particularly the most recent results of the LHC Run II, and discussions on further research directions within the high energy particle physics community including both theory and experiment sides. The main goal of the conference is to provide intense and lively discussions between experimentalists and theorists in research areas such as the Standard Model Physics and Beyond, the Higgs Boson, Supersymmetry, Heavy Quark Physics and Heavy Ion Physics as well as the recent progress in the high luminosity upgrades of the LHC and future colliders developments.

Search for neutral MSSM Higgs bosons decaying to a tau-antitau pair in the ATLAS detector produced with 13 TeV proton-proton collisions at the LHC 20m

We present the latest results in the search for Minimal Supersymmetric Standard Model (MSSM) neutral Higgs bosons decaying to a tau-antitau pair (H/A->TauTau). We consider tau-pair decays in the Leptonic-Hadronic (LepHad) and Hadronic-Hadronic (HadHad) modes. We analyse Run 2 data recorded with the ATLAS detector, produced with proton-proton collisions at a centre-of-mass energy of 13 TeV at the Large Hadron Collider (LHC). The background theory of the MSSM will be introduced as an extension to the Standard Model (SM) predicting these additional Higgs bosons with masses heavier than the SM Higgs Boson. The resulting limits on the production rates of the MSSM Higgs boson, which are used to constrain the theory, will be presented.

CMS-HF Calorimeter Upgrade for Run II 20m

CMS-HF Calorimeters have been undergoing a major upgrade for the last couple of years to alleviate the problems encountered during Run I, especially in the PMT and the readout systems. In this poster, the problems caused by the old PMTs installed in the detectors and their solutions will be explained. Initially, regular PMTs with windows thick enough to cause Cherenkov radiation were used. Instead of the light coming through the fibers from the detector, stray muons passing through the PMT itself produce Cherenkov radiation in the PMT window, resulting in erroneously large signals. Usually, large signals are the result of very high-energy particles in the calorimeter and are tagged as important. As a result, these so-called “window events” generate false triggers. Four-anode PMTs with thinner windows were selected to reduce these “window events.” Additional channels also help eliminate such remaining events through some algorithms comparing the output of different PMT channels. During the EYETS 16/17 period in the LHC operations, the final components of the modifications to the readout system, namely the two-channel front-end electronics cards, are installed. Complete upgrade of the HF Calorimeter, including the preparations for the Run II will be discussed in this poster, with possible effects on the eventual data taking.

SM Higgs boson decays to taus at CMS 20m

A search for a standard model Higgs boson decaying into a pair of tau leptons is performed using events recorded by the CMS experiment at the LHC in 2016. The dataset corresponds to an integrated luminosity of 35.9 fbinv at a center-of-mass energy of 13 TeV. Each tau lepton decays hadronically or leptonically, and the four final states with the largest branching fractions are considered.

Measurement of VBF Higgs boson production at sqrt(s)=13 TeV in the diphoton final state with the ATLAS detector 20m

A measurement of the VBF production cross section, performed in the framework of the Higgs simplified template cross section measurement, is made at sqrt(s)=13 TeV exploiting the diphoton final state. The measurement uses the full pp collision data collected in 2015 and 2016 by the ATLAS experiment at the LHC. Special emphasis is given to the optimisation of the selection and the uncertainty estimation.

Search for new physics in events with multileptons and jets in 35.9 fb−1 of pp collision data at 13 TeV with the CMS experiment 20m

A search for new physics is carried out in events with $\geq$ 3 electrons or muons and jets. Results are based on a sample of proton-proton collision data produced by the LHC at a center-of-mass energy of 13 TeV and collected by the CMS experiment in 2016. Events are classified according to the number of b-tagged jets, missing transverse momentum, hadronic transverse energy, and the invariant mass of opposite-charge, same-flavor dilepton pairs. The results are interpreted using simplified models of supersymmetry. No significant excess above the standard model background expectation is observed.

"Measurement of WW cross-section in pp collisions at 13TeV with the CMS detector 20m

A measurement of the W+W− cross section in pp collisions at 13 TeV is presented.
The data were collected with the CMS detector at the LHC in 2015, and correspond
to an integrated luminosity of 2.3 ± 0.1 fb-1 . The measurement is performed by selecting events with one electron and one muon of opposite charge, accompanied
by large missing transverse energy. The W+W− cross section is measured to be

$\rm D^{0}$-meson production and elliptic flow measurements in Pb--Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV with ALICE 20m

Heavy quarks (charm and beauty) are produced on a short time scale compared to the formation time of the Quark-Gluon Plasma (QGP) which is formed in heavy-ion collisions at ultra-relativistic energy. They propagate through and interact with the medium. Thus, they are powerful probes to study the properties of the QGP. The measurements of the nuclear modification factor and azimuthal anisotropy of D mesons allow us to investigate the parton energy loss mechanisms in the QGP and the transport properties of the medium.

In ALICE, D mesons are reconstructed in Pb-Pb collisions at central rapidity via their hadronic decay channels. The measurements of the $\rm D^{0}$ nuclear modification factor and azimuthal anisotropy in Pb--Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV in the centrality class 30-50\% will be presented and compared to the theoretical predictions.

A New US-CERN Summer Program on ATLAS Experiment of LHC at CERN for California State University System 20m

This abstract focuses on providing access to quality research opportunities for students from under represented groups through a summer research program through the Nuclear and Particle Physics Consortium at the California State University (CSU) system.

With over 460,000 students from a diverse range of backgrounds, the CSU system is the largest university system in the United states. It is also a minority serving institution. In 2013, the student body was 41% Latino (32% Mexican American) and 5% African American. At least 35% are the first person in their family to attend college. However, the campuses have limited research
opportunities for students. We will discuss a program started by Professor Yongsheng Gao of CSU Fresno, and supported by the NSF International Research Experiences for Students and other CSU campuses, to provide CSU students with summer research experiences at CERN with mentors from a variety of institutions. Students are prepared for the program by taking an online courses on particle physics taught by Professor Gao, and doing several months of practical tutorials with CSU Fresno and other ATLAS institutions (Stanford, UC-Irvine, Washington, etc.) postdocs. Our talk will focus on the preparation and experiences of both the student and mentors.

B \to \pi\pi transition form factor in LCSRs 20m

We study $B\to\pi\pi$ form factors using QCD light-cone sum rules with $B$-meson distribution amplitudes. These form factors describe the semileptonic decay $B\to \pi\pi \ell\bar{\nu}_{\ell}$, and constitute an essential input in $B\to \pi\pi \ell^+\ell^-$ and $B\to \pi\pi\pi$ decays. We employ the correlation functions where a dipion isospin-one state is interpolated by the vector light-quark current. We obtain sum rules where convolutions of the $P$-wave $\bar{B}^0\to \pi^+\pi^0$ form factors with the time-like pion vector form factor are related to universal $B$-meson distribution amplitudes. These sum rules are valid in the kinematic regime where the dipion state has a large energy and a low invariant mass, and reproduce analytically the known light-cone sum rules for $B\to \rho$ form factors in the limit of $\rho$-dominance with zero width, thus providing a systematics for so-far-unaccounted corrections to $B\to\rho$ transitions. Using data for the pion vector form factor, we estimate finite width-effects and the contribution of excited $\rho$-resonances to the $B\to\pi\pi$ form factors. We find that these contributions amount up to $\sim 20\%$ in the small dipion mass region where they can be effectively regarded as a nonresonant ($P$-wave) background to the $B\to\rho$ transition.

Bc → BsJ form factors and Bc decays into BsJ in covariant light-front approach 20m

We suggest to study the $B_s$ and its excitations $B_{sJ}$ in the Bc decays. We calculate the $B_c → B_{sJ}$ and $B_c → B_J$ form factors within the covariant light-front quark model, where the $B_{sJ}$ and $B_J$ denote an s-wave or p-wave $\bar b s$ and $\bar b d$ meson, respectively. The form factors at $q^2 = 0$ are
directly computed while their $q^2$-distributions are obtained by the extrapolation. The derived form factors are then used to study semileptonic $B_c → (B_{sJ} , B_J )\bar lν$ decays, and nonleptonic $B_c → B_{sJ} π$. Branching fractions and polarizations are predicted in the standard model. We find that the branching fractions are sizable and might be accessible at the LHC experiment and future high- energy $e^+e^−$ colliders with a high luminosity at the $Z$-pole. The future experimental measurements are helpful to study the nonperturbative QCD dynamics in the presence of a heavy spectator and also of great value for the spectroscopy study.

Constraining $Z^\prime$ widths from $p_T$ measurements in Drell-Yan processes 20m

We define a Focus Point (FP) Asymmetry, $A_{\rm FP}$, obtained by integrating the normalised transverse momentum distribution of either lepton produced in the Drell-Yan (DY) process below and above a point where a variety of popular $Z^\prime$ models all have the same magnitude.
For a given $Z^\prime$ mass the position of this FP is predictable, depending only on the collider energy and on the low transverse momentum cut chosen in the normalisation procedure.
The resulting $A_{\rm FP}$ is very sensitive to the $Z^\prime$ width, and can be used to constrain this parameter in experimental fits.

Dark Photon Search at A Circular e+e− Collider 20m

One of the interesting portals linking a dark sector and the standard model (SM) is the kinetic mixing between the SM $U(1)_Y$ field with a new dark photon $A'$ from a $U(1)_{A'}$ gauge interaction. Stringent limits have been obtained for the kinetic mixing parameter $\epsilon$ through various processes. In this work, we study the possibility of searching for a dark photon interaction at a circular $e^+e^-$ collider through the process $e^+ e^-\to \gamma A^{\prime *} \to \gamma \mu^+\mu^-$. We find that the constraint on $\epsilon^2$ for dark photon mass in the few tens of GeV range, assuming that the $\mu^+\mu^-$ invariant mass can be measured to an accuracy of $0.5\%m_{A'}$, can be better than $3\times 10^{-6}$ for the proposed CEPC with a ten-year running at 3$\sigma$ (statistic) level, and better than $2\times 10^{-6}$ for FCC-ee with even just one-year running at $\sqrt{s} = 240$ GeV, better than the LHC and other facilities can do in a similar dark photon mass range. For FCC-ee, running at $\sqrt{s}=160$ GeV, the constraint can be even better.

Data Scouting : A New Trigger Paradigm 20m

In 2011, the CMS collaboration introduced the concept of data scouting as an alternative strategy to normal data-taking technique, allowing to take data that otherwise would be rejected by the trigger filters. This special data flow, based on event-size reduction rather than event filtering, was exercised to maintain sensitivity to new light resonances decaying to jets, with very small online and offline resources allocated to it. The challenges implied by this new workflow and the solutions developed within the CMS experiment are shown. This technique is now a standard ingredient for CMS data-taking strategy. In this poster, the present status of data scouting in CMS and the improvements introduced in 2015 and 2016 is presented.

Double Parton Scattering of Electroweak Gauge Boson Productions at 13 TeV and 100 TeV Proton-Proton Colliders 20m

We study double parton scattering (DPS) processes in gauge boson plus two jets ($W/Zjj$) final state and same sign W bosons ($W^\pm W^\pm$) final state at pp-collider with $\sqrt{s}= 13$ TeV and 100 TeV. We compare two different double parton models. After that, we discuss the kinematic distribution features of DPS events, showing the existence of distinctive observables, which can be used to separate DPS from the single parton scattering backgrounds. The crucial physical quantity in DPS, $\sigma_{\rm eff}$ , is under detailed research in this work. The possibility of DPS being background of standard model processes is also studied.

Exotic Higgs Decays at the LHeC 20m

I will discuss the prospects of searching for exotic Higgs decays at the proposed Large Hadron Electron Collider (LHeC), which is a high luminosity electron-proton collider expected to run synchronously with the HL-LHC. Two examples will be presented, namely the invisible Higgs decay and the Higgs decaying to 4b via intermediate scalars. Compared to the HL-LHC, the LHeC is demonstrated to yield at least comparable sensitivity in the invisible Higgs channel and much better sensitivity in the Higgs to 4b channel. These results are very attractive if there is no available lepton collider which can copiously produce the Higgs boson before the end of the HL-LHC.

Factorization and Resummation for Jet Processes 20m

Jets not only display the behaviour of QCD over a wide range of energy scales, from hard colliding energy to the hadronization energy, but also contain important signatures of exotic physics, such as top quarks or particles beyond the SM. In particular, recently jet substructure observables are playing a central role in a large number of analyses at the LHC. Most of the theoretical discussion of these aspects has taken place in the context of MC simulation studies. However, MC analysis is not always good enough, and it is difficult to extract the key characteristics of individual substructure methods and reveal the relations between them. With this motivation, it is imperative to understand jet observables from the first principles QCD.

In our recent series papers we have constructed a new effective field theory which fully factorizes non-global jet observables for the first time. Our formalism provides the basis for higher-order logarithmic resummations of jet and other non-global observables. As a nontrivial consistency check, we used it to obtain explicit next-to-next-to-leading order results for all logarithmically enhanced terms in several different non global jet observables and verified those against numerical fixed order computations.

Flavor Changing Neutral Higgs Interactions with Top and Tau at Hadron Colliders 20m

A general two Higgs doublet model (2HDM) is adopted to study the signature of
flavor changing neutral Higgs (FCNH) decay
$\phi^0 \to t\bar{c}+\bar{t}c$ and $\phi^0 \to \tau\mu$, where
$\phi^0$ could be a CP-even scalar ($H^0$) or a CP-odd pseudoscalar ($A^0$)
as well as $t \to c h^0$.
Measurement of the light 125 GeV neutral Higgs boson ($h^0$) couplings at the
Large Hadron Collider (LHC) favor the decoupling limit or the alignment limit
of a 2HDM, in which gauge boson and diagonal fermion couplings of $h^0$
approach Standard Model values.
In such limit, FCNH couplings of $h^0$ are naturally
suppressed by a small mixing parameter $\cos(\beta-\alpha)$, while the
off-diagonal couplings of heavier neutral scalars $\phi^0$ are sustained by
$\sin(\beta-\alpha) \sim 1$.
We study physics background from dominant processes with realistic acceptance
cuts and tagging efficiencies. Promising results are found for the LHC running
at 13 or 14 TeV collision energies as well as future pp colliders
at 28 TeV, 33 TeV, or 100 TeV.

General Mass Insertion Expansion in Flavour Physics 20m

Calculating amplitudes for the flavor changing transitions in terms of
the off-diagonal elements of mass matrices (so called "mass
insertions") in the theory defined in "gauge basis" (before mass
matrix diagonalization) is the common technique in analyzing the
flavor structure of the New Physics models. I will present a general
method allowing to expand any QFT amplitude calculated in the
mass-eigenstates (physical) basis into series in mass insertions, to
any required order. The presented method is purely algebraic,
translating an amplitude written in the mass eigenbasis into mass
insertions series without performing diagrammatic calculations in
gauge basis. It can be applied for all types of mass matrices -
either Hermitian (scalar or vector), general complex (Dirac fermions)
or complex symmetric (Majorana fermions). In addition, proposed
expansion has been automatized in the form of publicly available
specialized Mathematica package,"MassToMI", which I briefly describe. The package allows to obtain analytical expressions directly relating flavor observables to
New Physics parameters without tedious and error-prone direct
calculation of Feynman diagrams with mass insertions as additional
vertices.

Geometric Scaling Analysis of Deep Inelastic Scattering Data Including Heavy Quarks 20m

An analytic massive total cross section of photon–proton scattering is derived, which has geometric scaling. A geometric scaling is used to perform a global analysis of the deep inelastic scattering data on inclusive structure function 𝐹2 measured in lepton–hadron scattering experiments at small values of Bjorken 𝑥. It is shown that the descriptions of the inclusive structure function 𝐹2 and longitudinal structure function 𝐹L are improved with the massive analytic structure function, which may imply the gluon saturation effect dominating the parton evolution process at HERA. The inclusion of the heavy quarks prevent the divergence of the lepton–hadron cross section,which plays a significant role in the description of the photoproduction region.

We also consider the experimental data on phi-meson production on nuclear targets, and we find that they present unusually small shadow corrections for the inclusive density in the midrapidity region.

Investigation of the fast timing capabilities of the Silicon sensors for the CMS high granularity calorimeter 20m

The High Granularity Calorimeter (HGCAL) is the technology choice of the CMS collaboration for the endcap calorimetry upgrade planned to cope with the harsh radiation and unprecedented in-time event pileup projected at the High Luminosity-LHC era. In this context, profiting from fast-timing information (~tens of picoseconds) embedded in the calorimeter would represent a unique capability for resolving information from individual collisions at the HL-LHC. This will enhance the reconstruction and physics capabilities of the CMS detector in terms of pileup mitigation and particle identification. The HGCAL is realized as a 52-layer sampling calorimeter, including 600m^2 of silicon sensors and 500m^2 of scintillators read by SiPMs. We present the concept and expected use of the precision-timing in the HGCAL, along with results from beam-tests of silicon sensors - both unirradiated and irradiated. We show that for signals in the silicon above a few tens of MIPs (minimum ionizing particles) the precision is of the order of 20ps.

Measurement of the Underlying Event in pp collisions at sqrt(s) = 13 TeV with the ALICE experiment at the LHC 20m

Large In LHC RUN II, the Large Hadron Collider restarted with luminosities close to the nominal performances, and with a centre-of-mass energy increase of around 60% with respect to the end of the LHC RUN I. At this new energy it is absolutely essential to restudy the general features of the pp interaction, in particular the soft or semi-hard bulk of particles that form the Underlying Event, which is defined to be the complementary activity with respect to the leading interaction.

The measurement of the Underlying Event allows us to access fundamental information on the hadron structure. This has important consequences for lepton and photon isolation, and also for jet calibration.

In order to estimate the contributions of the Underlying Event, we present a characterization of the event properties focusing on the orthogonal plane with respect to the beam direction: the primary charged particle with the highest transverse momentum - defined to be the leading charged particle - is used to give the energy scale of the interaction. Primary charged particle and energy densities are measured in different azimuthal regions with respect to the leading charged particle.

In this poster, the performance results relevant to Underlying Event measurement in pp collisions at sqrt(s) = 13 TeV will be shown.

Measurements of charm mixing and CP violation using $D^0\to K \pm \pi\mp$ decays 20m

Measurements of charm mixing and $CP$ violation parameters from the decay-time-dependent ratio of $D^0 \to K^+ \pi^-$ to $D^0 \to K^- \pi^+$ decay rates and the charge-conjugate ratio are reported. The analysis uses $\overline{B}\to D^{*+} \mu^- X$, and charge-conjugate decays, where $D^{*+}\to D^0\pi^+$, and $D^0\to K^{\mp} \pi^{\pm}$. The $pp$ collision data are recorded by the \lhcb experiment at center-of-mass energies $\sqrt{s}$ = 7 and 8 TeV corresponding to an integrated luminosity of 3~fb$^{-1}$ The data are analyzed under three hypotheses: (i) mixing assuming $CP$ symmetry, (ii) mixing assuming no direct $CP$ violation in the Cabibbo-favored or doubly Cabibbo-suppressed decay amplitudes, and (iii) mixing allowing either direct $CP$ violation and/or $CP$ violation in the superpositions of flavor eigenstates defining the mass eigenstates. The data are also combined with those from a previous LHCb study of $D^0\to K \pi$ decays from a disjoint set of $D^{*+}$ candidates produced directly in $pp$ collisions. In all cases, the data are consistent with the hypothesis of $CP$ symmetry.

Measurements of photon identification efficiencies with the 2015 and 2016 pp collision data in ATLAS at √= 13 TeV 20m

This poster presents the techniques to measure the photon identification efficiencies in the ATLAS experiment, on the proton-proton collisions collected at √s = 13 TeV, with an integrated luminosity of 3.2 fb−1 and 33.3fb-1 corresponding to 2015 and 2016. Three independent analyses have been exploited. One uses photons from radiative Z→llγ decays. The second extracts the shower shape properties of electrons from Z→ee decays and extrapolates them to photons. The third directly measures the efficiency on samples of reconstructed photons, after determining and subtracting the hadronic background with a technique based on track isolation. The results from all analyses are then compared with each other and with the prediction from the simulation.

miss 20m

Based on the framework of color glass condensate, we studied the hadron multiplicity distribution at the LHC energies, The full next-to-leading order Balitsky-Kovchegov(BK) equation is solved numerically, which obtain the NLO unintegrated gluon distribution (UGD) function in the coordinate space. We also extend the parton distribution function and the fragmentation function to NLO. A full NLO CGC particle production model is established in this study. When we compare the model calculations with charged hadron multiplicity experimental data from LHC, the results show the full NLO CGC model can describe the data very well.

Mono-Higgs search at LHC with the CMS detector 20m

We discuss a search for a dark matter (DM) pair production in association with a 125-GeV Higgs boson using the data collected at 13 TeV at the LHC using the CMS detector. This signature, dubbed "mono-Higgs," appears as a single Higgs boson plus missing energy from DM particles escaping the detector. The search exploits the large missing transverse energy and other kinematic variables to separate potential signal from the large SM background. The results are interpreted in the context of different simplified physics models.

The PandaX-III is a high pressure TPC concept to search for neutrinoless double-beta decay of Xe136 with high energy resolution and sensibility at the China Jin Ping underground Laboratory II (CJPL-II). Microbulk Micromegas will be used as a charge amplification and readout system in order to reconstruct both the energy and track of the neutrinoless double-beta decay event. In the first phase of the experiment, the detector, which contains 200 kg of 90% Xe-136 enriched gas operated at 10 bar, will be immersed in a large water tank to ensure 5 m of water shielding, so that we could get an excellent control over backgrounds.

Performance of the ATLAS hadronic Tile calorimeter 20m

The Tile Calorimeter (TileCal) of the ATLAS experiment at the LHC is the central hadronic calorimeter designed for reconstruction of hadrons, jets, tau-particles and missing transverse energy. TileCal is a scintillator-steel sampling calorimeter and it covers the region of pseudorapidity < 1.7. The scintillation light produced in the scintillator tiles is transmitted by wavelength shifting fibers to photomultiplier tubes (PMTs). The analog signals from the PMTs are amplified, shaped and digitized by sampling the signal every 25 ns. The TileCal frontend electronics reads out the signals produced by about 10000 channels measuring energies ranging from ~30 MeV to ~2 TeV. Each stage of the signal production from scintillation light to the signal reconstruction is monitored and calibrated.

The performance of the calorimeter has been studied in-situ employing cosmic ray muons and a large sample of proton-proton collisions acquired during the operations of the LHC. Prompt isolated muons of high momentum from electroweak bosons decays are employed to study the energy response of the calorimeter at the electromagnetic scale. The calorimeter response to hadronic particles is evaluated with a sample of isolated hadrons and the modelling of the response by the Monte Carlo simulation is discussed. The calorimeter timing calibration and resolutions are studied with jets.

Results on the calorimeter operation and performance are presented, including the calibration, stability, absolute energy scale, uniformity and time resolution. These results show that the TileCal performance is within the design requirements and has given essential contribution to reconstructed objects and physics results.

Probe CP violation through forward-backward asymmetry in $h\to \gamma Z \to \gamma l^-l^+$ process 20m

We show that the forward-backward asymmetry $(A_{FB})$ of the charged lepton in $gg\to H\to\gamma Z\to\gamma \ell^-\ell^+$ process could be used to probe the CP violating $H\gamma Z$ coupling when the interference of $gg\to\gamma Z\to\gamma \ell^-\ell^+$ process is included. In the presence of CP violation in $H\gamma Z$ coupling, the interference has a non-vanishing forward-backward asymmetry $(A_{FB})$, which is also sensitive to the strong phase differences. The resonant and non-resonant strong phases together make $A_{FB}$ change sign around Higgs mass $M_H$. We propose the integral over one-side mass region below (or above) $M_H$ to get a larger $A_{FB}$.

Production of extra quarks decaying to Dark Matter at the LHC beyond the Narrow Width Approximation 20m

Studying how ATLAS and CMS searches for supersymmetry in the t tbar + MET final state constrain scenarios with a fermionic top partner and a dark matter candidate, we show that the efficiencies of the considered searches are quite similar for scalar and fermionic top partners. Therefore, in general, efficiency maps for stop–neutralino simplified models can also be applied to fermionic top-partner models, provided the narrow width approximation holds in the latter. This motivates the exploration of finite width effects in the production and decay of extra heavy quarks at the LHC, this dynamics being normally ignored in standard experimental searches. For this reason we assess the regions of validity of current approaches and study the impact of the Dark Matter candidate spin on the exclusion.

SEARCH FOR DISPLACED LEPTON_JETS WITH THE ATLAS EXPERIMENT 20m

Several possible extensions of the Standard Model predict the existence of
a dark sector that is weakly coupled to the visible one: i.e. the two
sectors couple via the vector portal, where a dark photon with mass in the
MeV to GeV range mixes kinetically with the SM photon. If the dark photon
is the lightest state in the dark sector, it will decay to SM particles,
mainly to leptons and possibly light mesons. Due to its weak interactions
with the SM, it can have a non-negligible lifetime. At the LHC, these dark
photons would typically be produced with large boost resulting in
collimated jet-like structures containing pairs of leptons and/or light

This work is focused on the search for "displaced LJs", which are
produced away from the interaction point and their constituents are limited
to electrons, muons, and pions. The requested topology includes one or two
LJs + leptons/jets/MET. The most recent ATLAS results based on samples
collected at a center of mass energy of 13 TeV will be presented.

Results are interpreted in terms of the Falkowsky-Ruderman-Volansky-Zupan
models where dark photons are generated through the decay of a Higgs boson
to intermediate hidden fermions. The Higgs boson is supposed to be produced
via gluon-fusion and for the first time, results are also presented in
terms of the associated production of a Higgs boson with a W/Z and in the
context of inelastic thermal relic dark matter.

Search for heavy Higgs bosons decaying into a top quark pair in ATLAS 20m

Still many things in our nature can not be explained by the Standard Model.
Many of these conundrums could be addressed by some of the best motivated models currently
under exploration, such as super-symmetry (SUSY), composite Higgs models and
extended Higgs models such as two-Higgs doublet models (2HDM). Most of these
extensions require additional scalar bosons. In particular, the 2HDM proposes
two new heavier neutral Higgs bosons, a scalar H and a pseudoscalar A.
ttbar is a very important (or say dominant) decaying channel of A/H,
especially for low tan\beta. Searches for A/H through the
gg->A/H->ttbar process are very challenging due to the peculiar behaviour of the
large interference effects with the SM ttbar background. Such
effects distort the signal shape from the normal peak-structure to be peak-dip
co-existing, which makes the signal generation and statistics treatment very
different from the traditional ways. The invariant mass of the ttbbar
candidate pair is reconstructed under the assumption of a semi-leptonic ttbar
decay. The final state is characterised by a single, high-pT electron or muon, large MET, and at least
four jets. The analysis will be presented, it is also the first A/H->ttbar searching result at LHC.
The results are further interpreted in the type-II 2HDM model, on the tan\beta
exclusion for several different A/H masses.

SEARCHING FOR NEW HIGH MASS PHENOMENA DECAYING TO MUON PAIRS USING PROTON-PROTON COLLISIONS AT √ s = 13 TEV WITH THE ATLAS DETECTOR AT THE LHC 20m

The Standard Model (SM) of particle physics is a very successful predictive theory which explains the fundamental
interactions of elementary particles in the universe, except for gravity. However, the SM is known to be an effective
theory that is valid only in a low energy regime, called the elctroweak scale, and does not account for many observed
experimental results. For example, it does not offer a satisfying explanation for neutrino masses or dark matter. Hence,
it is clear that to fully understand and explain nature, a theoretical framework that goes beyond the Standard Model
(BSM) is required. While high mass resonances do not offer a complete solution to the problems mentioned above,
many BSM theories predict their existence. To name a few, extra dimensional models, grand unified theories, and
supersymmetric models all have the common goal of reconciling the very different scales of electroweak symmetry
breaking and high mass scales, and predict the existence of high mass resonances. Thus, finding high mass resonances
would help validate these theories, which do offer solutions to the aforementioned problems.
This analysis focuses on searching for new high mass phenomena using the latest data collected by the ATLAS
detector at the LHC, which has an unprecedented centre-of-mass energy of 13 TeV and corresponds to 36.5 fb−1
at √s= 13 TeV. The search is conducted for both resonant and non-resonant new phenomena in dimuon final states. The
dimuon invariant mass spectrum is the discriminating variable used in this search. No significant deviations from the
Standard Model expectation are observed. Lower limits are set on the signal parameters of interest at 95% credibility
level, using a Bayesian interpretation.

Searching for Singlino-Higgsino Dark Matter in the NMSSM 20m

We study a simplified scenario in the next-to-minimal supersymmetric standard model with a split electroweak spectrum, in which only the singlino and higgsinos are light and other superpartners are decoupled. Serving as a dark matter candidate, a singlino-dominated neutralino $\tilde{\chi}_1^0$ should have either resonant annihilation effects or sizable higgsino components to satisfy the observed relic abundance. The sensitivities of LHC searches and dark matter detection experiments are investigated. With an integrated luminosity of $30~(300)~\mathrm{fb}^{-1}$, $3l + E_\mathrm{T}$ and $2l + E_\mathrm{T}$ searches at the 13~(14)~TeV LHC are expected to reach up to $m_{\tilde{\chi}_1^0} \sim 150~(270)~\mathrm{GeV}$ and $m_{\tilde{\chi}_2^0,\tilde{\chi}_1^{\pm}}\sim 320~(500)~\mathrm{GeV}$.

Simulation of the ATLAS New Small Wheel (NSW) System 20m

The instantaneous luminosity of the Large Hadron Collider (LHC) at CERN will be increased up to a factor of five with respect to the present design value by undergoing an extensive upgrade program over the coming decade. In order to benefit from the expected high luminosity performance that will be provided by the Phase-1 upgraded LHC, the first station of the ATLAS muon end-cap Small Wheel system will need to be replaced by a New Small Wheel (NSW) detector. The NSW is going to be installed in the ATLAS detector in the forward region of 1.3 < |η| < 2.7 during the second long LHC shutdown. The NSW will have to operate in a high background radiation region, while reconstructing muon tracks with high precision as well as furnishing information for the Level-1 trigger. A detailed study of the final design and validation of the readout electronics for a set of precision tracking (Micromegas) and trigger chambers (small-strip Thin Gap Chambers or sTGC) that are able to work at high rates with excellent real-time spatial and temporal resolution will be presented. The simulation of the entire NSW system integrated in the common ATLAS trigger simulation and reconstruction chain is a necessary part of the performed Monte Carlo (MC) studies. A dedicated parametric digitization model based on the exhaustive standalone MC studies and experimental test beam results has been developed over the years to simulate the response of the NSW system. The simulated digital readout signals are used to build the cluster hits and reconstructed track-segments in the detector planes at both the trigger and off-line reconstruction levels. They have been included in the common ATLAS muon trigger and reconstruction algorithms. This contribution will summarize the developed simulation model and the importance of the NSW system for the improvement of the muon reconstruction efficiency and muon identification.

the services, etc.) did not allow for accurate modelling of the planned
detector design. A range of sensors/layouts for the Strip tracker are being
considered and must be studied in detailed simulations in order to assess the
performance and ascertain that requirements are met. For this, highly
flexibility geometry building is required from the simulation software. A new
Xml-based detector description framework has been developed to meet the
aforementioned challenges. We will present the design of the framework and its
validation results.

Standard Model Extended by a Heavy Singlet: Linear vs. Nonlinear EFT 20m

I consider the Standard Model extended by a heavy scalar singlet and derive the low-energy effective theory resulting from integrating out the heavy state. This exercise in effective field theory serves to illustrate with a simple example the systematics of the linear and nonlinear electroweak effective Lagrangians and to clarify the relation between them. I discuss power-counting aspects and the transition between both effective theories on the basis of the model.

Studies of $Z\gamma$ electroweak production in association with a high-mass dijet system in pp collisions at $\sqrt{s}$ = 8 TeV with the ATLAS detector 20m

The production of a $Z$ boson and a photon in association with a
high-mass dijet system is studied using 20.2 fb$^{-1}$ of
proton–proton collision data at a centre-of-mass energy of $\sqrt{s} = 8$ TeV
recorded with the ATLAS detector in 2012 at the Large Hadron Collider.
Final states with a photon and a Z boson decaying into a pair of either electrons,
muons, or neutrinos are analysed. Electroweak and total $pp \to Z\gamma j j$
cross-sections are extracted in two fiducial regions with different sensitivities to
electroweak production processes. Quartic couplings of vector bosons are studied
in regions of phase space with an enhanced contribution from pure electroweak
production, sensitive to vector-boson scattering processes $VV \to Z\gamma$.
No deviations from Standard Model predictions are observed and constraints are placed on
anomalous couplings parameterized by higher-dimensional operators using effective field theory.

Study of doubly heavy baryon decays in light-front approach 20m

In this work, we study the transition processes of doubly heavy baryons
$\Xi_{cc}^{++}$, $\Xi_{cc}^{+}$, $\Omega_{cc}^{+}$, $\Xi_{bc}^{+}$,
$\Xi_{bc}^{0}$, $\Omega_{bc}^{0}$ and $\Omega_{bb}^{-}$. At the
quark level these transtions are depicted by the weak decays of $c\to d/s$
or $b\to u$ and the other two spectator quarks are viewed as a scalar
diquark. We first derived the form factors of these transtions in
light-front approach and then apply them to predict the semi-leptonic
and non-leptonic decay widths of doubly heavy baryons. We find that
some decay channels are sizable and are hopeful to be detected at
the LHC experiment.

Study of Higgs boson properties in H->ZZ^(*)->4l decay channel with ATLAS 20m

After the discovery of the Higgs boson, the precision measurements of its properties
and comparison of results to those predicted by the Standard Model (SM) became the crucial
part of the LHC physics programme. Potential observation of deviations may lead to the
discovery of a new physics beyond the Standard Model (BSM). In this contribution, the results of
analyses of the Higgs boson properties in H->ZZ*->4l decay channel are presented. The
measurements of Higgs SM couplings, fiducial and differential cross sections with
36.1 fb -1 of data collected by ATLAS at sqrt s = 13 TeV are shown. The observed limits on BSM
tensor structure of Higgs couplings to SM bosons and fermions are also discussed.

Study of the Material within the Run II ATLAS Inner Detector 20m

The material in the ATLAS Inner Detector (ID) is studied with several methods, using a sample of √s=13 TeV pp collisions
collected in 2015 during Run II of the LHC. The material within the innermost barrel regions of the ID is studied using
reconstructed secondary vertices from hadronic interactions and photon conversions. The layout of the cables, cooling p
ipes and support structures (services) associated with the Pixel detector, in the region in front of the Silicon Microstrip detector (SCT), was modified in 2014. The material in this region was studied by measuring the efficiency with which tracks reconstructed only in the Pixel detector can be matched to tracks reconstructed in the full ID (track extension efficiency). The results of these studies are presented together with a comparison to previous measurements and a description of their impact on physics analyses and Monte Carlo simulation.

Studying WVγ production in proton-proton collisions at √s = 8 TeV with the ATLAS experiment 20m

Quartic gauge couplings are tested by this study of the production of WVγ events (where V = W or Z) in
20.2 fb−1 of proton-proton collisions at a centre-of-mass energy of √s = 8 TeV recorded with the ATLAS detector. The
fully-leptonic final state of WWγ events containing an electron, a muon and a photon is analysed as well as
semi-leptonic final states of WVγ production containing an electron or a muon, two jets and a photon. For all final
states two different fiducial regions are defined: one yielding the best sensitivity to the production cross section of the
process and one optimised for the detection of new physical phenomena. In the former region, the WWγ production
cross section is computed using the fully-leptonic final state. In addition, upper limits on the production cross section
are derived in both regions for all final states individually and for the combination of the semi-leptonic final states. The
results obtained in the new physics phase space are combined for the interpretation in the context of anomalous
quartic gauge couplings using an effective field theory.

The ATLAS Run-2 Trigger Menu for higher luminosities: Design, Performance and Operational Aspects 20m

The LHC, at design capacity, has a bunch-crossing rate of 40 MHz whereas the ATLAS experiment has an average recording rate of about 1 kHz. To reduce the rate of events, but maintain high selection efficiency for rare events such as physics signals beyond the Standard Model, a two-level trigger system is used. Events are selected based on physics signatures such as presence of energetic leptons, photons, jets or large missing energy. Despite the limited time available for processing collision events the trigger system is able to exploit topological information, as well as using multi-variate methods. In total, the ATLAS trigger systems consists of thousands of different individual triggers.

The ATLAS trigger menu specifies which triggers are used during data taking and how much rate a given trigger is allocated. This menu reflects not only the physics goals of the collaboration but also takes into consideration the instantaneous luminosity of the LHC and the design limits of the ATLAS detector and offline processing farm. For 2017 data taking, the trigger selections and menus have been improved to handle expected higher luminosities of up to 2.0x10^{34}cm^{-2}s^{-1} and to ensure robustness in the presence of multiple interactions per bunch crossing.

We describe the criteria for designing the ATLAS trigger menu used for the LHC Run 2 period. Furthermore, we discuss how the trigger menu is deployed for data taking, through different phases: validation before deployment, decisions on prescale values for different triggers (ahead of running, or live in case of sudden rate changes), and monitoring during data taking itself.

As the result of 120kg PandaX-I has been released in May 2015 and the 500kg PandaX-II will stop data taking in 2018, the upgraded experiment, PandaX-IV, will contain 4 tons of xenon in the sensitive volume and we hope it will set the more stringent limit for WIMP.

The Particle nature of Mini Black Hole at LHC 20m

We discuss quantum mechanical directions where a mini black hole at LHC behaves like a "particle", even if with a unique property: its linear size grows with the energy. The curved dynamics is explained in terms of a particle moving in gravitational potential. The particle turning-points match the radius of the inner and outer horizons of a Reissner–Nordström black hole. Further we compute a particular form of the wave function and determine the energy spectrum in present talk.

The production of additional bosons and the impact on Higgs boson physics 20m

In Refs. arXiv:1506.0061 and arXiv:1606.0167 the compatibility of LHC data taken until 2012 with a heavy scalar with a mass around 270 GeV have been discussed. The features of the data and the phenomenological framework studied there are reviewed. A number of predictions are made, including the anomalous production of multiple leptons. The decay of this heavy scalar includes the Higgs boson. The impact on a number of observables related to the measurement of the signal strengths of the Higgs boson at the LHC is discussed.

Transverse momentum resummation for t-channel single top quark production at the LHC 20m

We study the soft gluon radiation effects for the $t$-channel single top quark production at the LHC.
By applying the transverse momentum
dependent factorization formalism, the large logarithms about the small total transverse momentum ($q_\perp$)
of the single-top plus one-jet final state system, are resummed
to all orders in the expansion of the strong interaction coupling at the accuracy of Next-to-Leading Logarithm(NLL).
We compare the singular behavior of resummation calculation to fixed order prediction at the small $q_\perp$ region,
and find a perfect agreement. The phenomenological importance of the resummation effect at the
LHC is also demonstrated.

Upgrade of the ATLAS hadronic Tile calorimeter for the High luminosity LHC 20m

The Tile Calorimeter (TileCal) is the hadronic calorimeter covering the central region of the ATLAS detector at the LHC. It is a sampling calorimeter consisting of alternating thin steel plates and scintillating tiles. Wavelength shifting fibers coupled to the tiles collect the produced light and are read out by photomultiplier tubes. Currently, an analog sum of the processed signal of several photomultipliers serves as input to the first level of trigger. Photomultiplier signals are then digitized and stored on detector and are only transferred off detector once the first trigger acceptance has been confirmed.

The Large Hadron Collider (LHC) has envisaged a series of upgrades towards a High Luminosity LHC (HL-LHC) delivering five times the LHC nominal instantaneous luminosity. The ATLAS Phase II upgrade, in 2024, will accommodate the detector and data acquisition system for the HL-LHC. In particular, TileCal will undergo a major replacement of its on- and off-detector electronics. All signals will be digitized and then transferred directly to the off-detector electronics, where the signals will be reconstructed, stored, and sent to the first level of trigger at a rate of 40 MHz. This will provide better precision of the calorimeter signals used by the trigger system and will allow the development of more complex trigger algorithms. Changes to the electronics will also contribute to the reliability and redundancy of the system.

Three different front-end options are presently being investigated for the upgrade. Results of extensive laboratory tests and with beams of the three options will be presented, as well as the latest results on the development of the power distribution and the off-detector electronics.

​ Measurements of integrated and differential cross sections for isolated photon pair production in pp collisions at sqrt{s} = 8 TeV with the ATLAS detector 20m

A measurement of
the production cross section for two isolated photons in proton-proton collisions at a
centre-of-mass energy of √ s = 8 TeV is presented. The results are based on an integrated luminosity of 20.24 fb−1
recorded by the ATLAS detector at the Large Hadron Collider. The measurement considers photons with
pseudorapidities satisfying |η γ | < 1.37 or 1.56 < |η γ | < 2.37 and transverse energies of respectively Eγ T,1 > 40
GeV and Eγ T,2 > 30 GeV for the highest and second highest Eγ T photon produced in the interaction. The
background due to hadronic jets and electrons is subtracted using data-driven techniques. The fiducial cross
sections are corrected for detector effects and measured differentially as a function of six kinematic observables. The
data are compared to fixed-order QCD calculations at 16 next-to-leading order (NLO) and
next-to-next-to-leading-order (NNLO) accuracy as well as NLO computations including resummation of initial-state

A search and measurement of Standard Model Higgs boson decay to $\mu^+\mu^-$ at CEPC 15m

A Search and measurement at Circular Electron Positron Collider (CEPC) is reported for Higgs Boson rare decay to $\mu^+\mu^-$, of which the SM branch ratio is $2.19 \times 10^{-4}$. This is an important channel to further examine the Higgs couplings with second generation of fermions. The analysis is performed on 240GeV CEPC with expected 5ab-1 luminosity in 10 years, with GEANT4-based full simulation.
The significance can reach 7.1 standard deviations ($\sigma$) in the model-independent analysis which uses only the information of Z boson decay, while can be 8.2 and 2.1$\sigma$ in the exclusive $Z\to qq$ and $Z \to \nu\nu$ channels, respectively. Impact of the Magnetic Field Strength and Tracker size to these measurements are further investigated
