Dr Olaf Kaczmarek (University of Bielefeld)01/08/2016, 14:00Transport properties and probesTalkWe estimate the photon production rate from an SU(3) plasma at temperatures of about $1.1~T_c$ and $1.3~T_c$. Lattice results for the vector current correlator at spatial momenta $k\sim (2-6)T$ are extrapolated to the continuum limit and analyzed with the help of a polynomial interpolation for the corresponding spectral function, which vanishes at zero frequency and matches to...Go to contribution page

Mr Atsuro Ikeda (Osaka University)01/08/2016, 14:25Transport properties and probesTalkWe study the transport coefficient for the charm quark in the deconfined phase from correlator in the temporal channel with nonzero momentum on the quenched lattice. Lattice Euclidean correlator in the temporal channel with zero momentum is constant as a function of the imaginary time because of the charge conservation. However, the derivative of the correlator with respect to momentum...Go to contribution page

Dr Victor Braguta (ITEP)01/08/2016, 14:50Transport properties and probesTalkThis report is devoted to the study of temperature dependence of shear viscosity in SU(3)-gluodynamics. To calculate shear viscosity we measured the correlation function of the energy-momentum tensor T_{12}T_{12} for a set of temperatures in the region T/T_c \in (0.9, 1.5). The measurements were carried out using multilevel algorithm which considerably improves the accuracy of the...Go to contribution page

Dr Yusuke Taniguchi (University of Tsukuba)01/08/2016, 15:15Transport properties and probesTalkWe apply the gradient flow method to Nf=2+1 full QCD at finite temperature. Our main interest is on temperature dependence of: 1. energy-momentum tensor with quark contribution, 2. chiral condensate and its susceptibility. We show that these observables are well measured with the gradient flow method. Our finite temperature system is constructed by fixing the lattice spacing and...Go to contribution page

Dr Jorge Casalderrey Solana (University of Oxford)01/08/2016, 16:10Transport properties and probesTalkWe numerically simulate gravitational shock wave collisions in a holographic model dual to a non-conformal four-dimensional gauge theory. We find two novel effects associated to the non-zero bulk viscosity of the resulting plasma. First, the hydrodynamization time increases. Second, if the bulk viscosity is large enough then the plasma becomes well described by hydrodynamics before the...Go to contribution page

Prof. Seyong Kim (Sejong University)01/08/2016, 16:35Transport properties and probesTalkThe thermal Sommerfeld factor, concerning the co-annihilation rate of heavy quarks in thermal equilibrium, is shown that it can be defined in terms of two-point correlator ratios. Then, we calculate non-perturbatively the co-annihilation rate of heavy quarks close to thermal equilibrium using lattice NRQCD framework. Lattice measurements indicate a modest suppression in the octet channel,...Go to contribution page

Mr Kazuya Mameda (The University of Tokyo)01/08/2016, 17:00Bulk properties of the quark-gluon plasmaTalkIn nonrelativistic many-body systems, rotation produces interesting phenomena as well as external electromagnetic field and finite chemical potential. On the other hand rotational effects on relativistic systems have not been elucidated. Nevertheless it is known that a rapid rotation is realized in main objectives of QCD physics: heavy-ion collisions and neutron stars. In this talk, we...Go to contribution page
