Direct Photon Production in Au+Au Collisions at RHIC-PHENIX Experiment

Abstract

Direct photons have been measured with the PHENIX experiment in Au+Au collisions at $\sqrt{s_{\mathrm{NN}}}$ = 200 GeV. The direct photon result obtained with PHENIX-EMCal up to 18 GeV/$c$ is consistent with the NLO pQCD calculation scaled by the nuclear overlap function. The measurement using internal conversion of photons into $e^{+}{e}^{-}$ shows the enhancement of the yield comparing with NLO pQCD calculation.
