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

Direct photons have been measured with the PHENIX experiment in Au+Au collisions at . 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.
