Direct Photon Production in Au+Au Collisions at RHIC-PHENIX Experiment
Tadaaki Isobe
Abstract
Direct photons have been measured with the PHENIX experiment in Au+Au collisions at sNN = 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.
