11th International Conference on Hard and Electromagnetic Probes of High-Energy Nuclear Collisions

We use QCD kinetic theory to compute photon production in the chemically equilibrating out-of-equilibrium Quark-Gluon Plasma created in the early stages of high-energy heavy-ion collisions. We compare the non-equilibrium rates to the production in a thermal QGP and extract the dependence of pre-equilibrium photon production on the kinetic and chemical equilibration time. This allows us to include realistic pre-equilibrium photon production in heavy-ion collisions.
