Prof. Defu Hou (Central China Normal University)parallelThe gluon polarization tensor for the quark-gluon plasma with shear viscosity is derived with the viscous chromohydrodynamics. The longitudinal and transverse dielectric functions are evaluated from the gluon polarization tensor, through which the polarization energy loss suffered by a fast quark traveling through the viscous quark-gluon plasma is investigated. The numerical analysis indicates...Go to contribution page

Dr Anton Wiranata (CCNU)parallelThe ratio $\eta/s$ of the shear viscosity, $\eta$, and the entropy density, s, of hot interacting hadrons is calculated using the Chapman-Enskog and virial expansion methods. Interactions are parametrized using the K-matrix which preserves the unitarity of the S-matrix. In the four component mixture $\pi-K-\eta-N$, 57 resonances up to 2 GeV are included. Increasing number of resonances is...Go to contribution page
