Description
We derive the transport coefficients of a two component Hadronic gas consisting of Pions and Nucleons. We solve the relativistic Boltzmann equation with binary collision ($\pi\pi$, $\pi N$ and $NN$) employing the relaxation time approximation method. In medium effects are introduced through one loop self-energies in the propagator of the exchange of $\rho$ and $\sigma$ for the $\pi\pi$ cross-section, and one loop self-energy in the propagator of the exchange of $\Delta$ for the $\pi N$ cross-section. We use phenomenological amplitude for $NN$ collisions. The effect of early freeze-out in heavy collision is implemented through temperature dependent pion chemical potential. The temperature dependence of the transport coefficients are studied.
