Seminar in Hadronic PhysicsDynamical photon production in partonic transportMoritz GreifGoethe University FrankfurtPartonic transport approaches have proved to be valuable tools in describing the quark-gluon plasma, created in heavy-ion collisions. In this work, first steps towards a dynamical understanding of photon production in expanding heavy-ion collisions are presented. Several photon production processes are included in the partonic cascade BAMPS (Boltzmann Approach to Multi-Parton Scatterings). BAMPS provides a microscopic tool to study expanding fireballs, employing a stochastic method to solve the relativistic 3+1d Boltzmann equation for quarks, gluons and photons. The partonic cascade is applicable over the whole evolution of the plasma, thus giving insights also about the early, off-equilibrium phase. Photon spectra of the quark-gluon plasma are investigated, and in particular, the influence of the pre-equilibrium phase for the elliptic flow of photons is studied in detail.
