Monte Carlo studies for direct photon measurement with the ALICE EMCAL detector — •Dominik Herzig for the ALICE collaboration — Institur für Kernphysik Frankfurt

Since direct photons are produced during all stages of a heavy-ion collision, they can probe the space-time evolution of the medium. Direct photons sources include hard scattering processes, thermal emission and interactions of fast partons with the medium. In proton-proton collisions, direct photons are a vital tool to test pQCD calculations of hard processes. Furthermore, the pp-measurement is needed as a baseline for interpreting the heavy-ion data.

In the ALICE experiment the EMCAL detector is used to measure high energetic photons. In this poster, we present Monte Carlo studies for the analysis of direct photon production using the ALICE EMCAL. The poster focuses on improving photon identification cuts that are studied in such Monte Carlo simulations in order to test their effects on the photon measurement.
