Abstract

Using the second order Israel–Stewart hydrodynamics we discuss the effect of viscosity on photon production in a parton plasma created in relativistic heavy ion collisions. We find that photon production rates can be enhanced by several factors due to the viscous effect in a chemically nonequilibrated plasma.
