Direct Photon Measurement at RHIC-PHENIX

Abstract

Results on direct photon measurements from the PHENIX experiment at RHIC are presented. The direct photon yields for pT>p_T>6 GeV/cc as a function of centrality in Au-Au collisions at sNN\sqrt{s_{NN}}=200 GeV are found to be consistent with NLO pQCD calculation scaled by the number of binary collisions. The results suggest that the photons observed are emitted from the initial stage of hard scattering. Comparisons with several theoretical calculations are also presented.
