Type: Talk Session: Quarks and gluons in hot and dense matter
Track: 1) Quarks and gluons in hot and dense matter
Suppression of $J/\psi$ production in heavy-ion collisions due to color screening of quark and antiquark potential in the deconfined medium has been proposed as a signature of quark-gluon plasma (QGP) formation. However, there are other effects that may alter the observed $J/\psi$ yields, such as cold nuclear matter effects, and statistical coalescence of c-$\bar{\mathrm{c}}$ pairs. Indeed, recent ... More

We study the effects of the decuplet-octet mass difference for the baryon axial vector current at one-loop order in large-Nc baryon chiral perturbation theory, where Nc is the number of color. The baryon axial vector current is considered within the combined framework of large-Nc baryon chiral perturbation theory and the baryon axial vector couplings are extracted. We extend the g_A analysis by in ... More

Pb nuclei, accelerated at LHC, are sources of strong electromagnetic fields that can be used to measure photon-induced interactions in a new kinematic regime. These interactions can be studied in ultra-peripheral p-Pb and Pb-Pb collisions where impact parameters are larger than the sum of nuclear radii and hadronic interactions are strongly suppressed. Heavy quarkonium photoproduction is of pa ... More

Anisotropies of the azimuthal hadron distributions measured in nuclear collisions at highest energies carry information about the anisotropies of collective transverse expansion.

Gravitational accretion of dark matter in neutron stars may constitute a mechanism to check for further indirect effects of its existence. In this way, dark matter annihilations taking place within such compact astrophysical objects may prevent the appearance of additional particle population of hadrons inside the neutron star core.

The heavy quark hadrons are suggested as a clean probe for studying the early dynamic evolution of the dense and hot medium created in high-energy nuclear collisions. The Heavy Flavor Tracker (HFT) of the STAR experiment, designed to improve the vertex resolution and extend the measurement capabilities in the heavy flavor domain, was installed for the 2014 heavy ion run of RHIC. It is composed of ... More

At the quantum level, an interaction of a neutrino with a graviton may trigger the collapse of the neutrino flavor eigenstate to a neutrino mass eigenstate. I will present that such an essentially quantum gravity effect may have strong consequences for neutrino oscillation phenomena in astrophysics due to the relatively large scattering cross section of relativistic neutrinos off massive ...

The Pierre Auger Observatory is the world's largest cosmic ray observatory.  The observatory combines two complementary detection techniques to study the extensive particle showers created by collisions of primary cosmic rays with the atmosphere.  Analysis of those showers enables one not only to estimate the energy, direction and most probable mass of the primary cosmic particles, but also to o ...

We obtain a model independent expression for the muonic hydrogen Lamb shift. The hadronic effects are controlled by the chiral theory, which allows for their model independent determination. We give their complete expression including the pion and Delta particles. Out of this analysis and the experimental measurement of the muonic hydrogen Lamb shift we determine the electromagnetic proton radi ... More

The nEXO Collaboration is designing a very large detector for neutrino-less double beta decay of Xe-136. The nEXO detector is rooted in the the currently-running EXO-200 program, which has reached a sensitivity for the half life of the decay of 1.9 x 10^25 years with and exposure of 99.8 kg-yr. The baseline nEXO design uses 5 tonnes of liquid xenon, enriched in the mass 136 isotope, in a time p ... More

An observation of neutrinoless double-beta decay ($0\nu\beta\beta$) identifies the neutrino as a Majorana particle and constrains the absolute mass scale of neutrinos. The {\sc Majorana} collaboration is constructing an array of high purity germanium detectors that are isotopically enriched in $^{76}$Ge that will serve as both a source and detector of $0\nu\beta\beta$. In the presence of backgroun ... More

We present our studies of the Timelike Compton Scattering (TCS) process off the nucleon (gamma N -> N gamma* -> e+e-). At sufficiently large virtuality of the nal state photon, this reaction provides access, via a QCD factorization theorem, to the Generalized Partons Distributions (GPDs) of the nucleon. GPDs contain, in particular, informations about the correlations between the longitudin ... More

The future precision studies of the Standard Model require excellent knowledge of the top quark mass, to an accuracy of 100 MeV or better. A threshold scan in e+e- annihilation enables a precise measurement in theoretically well-defined mass schemes. The measurement requires a combination of precise QCD calculations, excellent detection efficiency and recognition of top quark events, and excellent ... More

The transverse momentum distributions (pT) of charged particles and identi ed hadrons in p-Pb collisions at sqrt(sNN) = 5.02 TeV have been measured by ALICE at the LHC. Charged-particle tracks are reconstructed at mid-rapidity over a large momentum range 0.15 < pT < 50 GeV/c. Light-flavoured hadrons and resonances are identi ed in the various momentum ranges from 0.15 GeV/c up to 15 GeV/c by u ... More

The Sivers function $f^{\perp}_{1T}$ describes the correlation of parton transverse momentum with the transverse spin of the nucleon. There is evidence of a quark Sivers effect in semi-inclusive DIS (SIDIS) measurements. In SIDIS, the quark Sivers function is associated with a final state effect from the gluon exchange between the struck quark and the target nucleon remnants. On the other hand, ... More

The dependence of the spectra shape of produced charged hadrons on the size of a colliding system is discussed using a two component model. As a result, the hierarchy by the system-size in the spectra shape is observed. Next, the extension of the two component model accounting for the 'collective flow' using recent theoretical calculations is suggested to describe the spectra of charged particles ... More

Ultra-slow muons, which are positively charged muons having an energy of a few eV, are useful tools for producing variable-energy muon beams with extraordinarily small energy spread by accelerating them through an electrostatic field. We will apply this new technique to a measurement of the muon anomalous magnetic moment g-2 and electric dipole moment at J-PARC [1], which requires an intense muon ... More

The Tile Calorimeter (TileCal) is the central hadronic calorimeter of the ATLAS experiment at LHC. Around 2023, after the upgrade of the LHC (High Luminosity LHC, phase 2) the peak luminosity will increase by a factor of 5 compared to the design value (10^34 cm^-2 s^-1), thus requiring an upgrade of the TileCal readout electronics.

Due to color screening, the production of quarkonia in high energy heavy ion collisions is expected to be sensitive to the energy density of the medium. Sequential suppression of different quarkonium states may therefore serve as a thermometer of the medium. Although the suppression of charmonia was anticipated as a key signature of the QGP, the observed energy dependence of $J/\psi$ suppression i ... More

In the gauge/gravity duality, the deconfinement transition in the gauge theory is identified with a formation of black hole in the dual gravity theory. By assuming this correspondence, many predictions on QGP have been made. In this talk, we justify this approach quantitatively, and also provide intuitive understanding. Firstly we give quantitative evidence for this identification from the thermod ... More

High energy photons have been measured in heavy ion collisions, at both RHIC and LHC. The direct photons, not from decay, carries a special information of the expanding system. This is studied with (3+1)-dimensional ideal hydrodynamics, constrained with a large collection of data of various hadrons. Thus a comparison between a realistic calculation and the photon data from both RHIC and LHC will b ... More
