Direct photon production from viscous QGP

Nuclear Theory 2015-03-17 v1 High Energy Physics - Phenomenology

Abstract

We simulate direct photon production in evolution of viscous QGP medium. Photons from Compton and annihilation processes are considered. Viscous effect on photon production is very strong and reliable simulation is possible only in a limited pTp_T range. For minimally viscous fluid η/s\eta/s=0.08), direct photons can be reliably computed only up to pTp_T \leq 1.3 GeV. With reduced viscosity (η/s\eta/s=0.04), the limit increases to pTp_T \leq 2GeV.
