Description
We evaluate transport coefficients in the kinetic approach explicitly including medium effects in the collision term. For the case of a pion gas the temperature dependence of shear and bulk viscosities as well as thermal conductivity evaluated in the Chapman-Enskog approach show significant medium dependence which enter via the pion-pion scattering cross-section. The in-medium rho and sigma propagators used here also affect the relaxation of dissipative flows evaluated using the Grad'd 14-moment method. Results for a interacting gas of pions and nucleons will be presented.
