Transport coefficients of a hot pion gas
Description
General expressions for transport coefficients of a single component gas (namely thermal conductivity, shear and bulk viscosities) of bosons are derived from a Boltzmann-Uehling-Uhlenbeck transport equation by means of the Chapman-Enskog method to first order. These expressions are then used for the calculation of the associated transport relaxation times and applied to the pion gas produced in ultra-relativistic heavy-ion collisions. The influence of Bose enhancement factors on transport properties can be seen by comparison with previous calculations. (authors)
