Numerical Results for Transport Coefficients of Quark Gluon Plasma with Iwasaki's Improved Action

Abstract

Numerical results for the transport coefficients of quark gluon plasma are calculated by lattice simulation of SU(3) pure gauge model. The bulk viscosity is consistent with zero. The shear viscosity is finite and increases with temperature $T$ roughly as $T^3$, and around the finite temperature transition points, it is slightly smaller than the typical hadron masses.
