Abstract
The study of transport properties of strongly interacting matter has captured much attention in recent times. The interpretation of experimentally measured elliptic flow of hadrons in RHIC, by nearly ideal hydrodynamics with a small value of η/s, close to the quantum bound 1/4π, provides much interest towards the transport coefficients, which characterize the response of an out of equilibrium system to certain disturbances. Our aim is to determine the shear and bulk viscous coefficients and as well as the thermal conductivity for an interacting pion gas by solving relativistic transport equation in kinetic theory approach. For the dynamical input we need to construct a medium dependent ππ cross-section which gives noticeable effects on the temperature of viscous coefficients and thermal conductivity.
