Description
Results from the PHENIX experiment on direct-photon production in Au+Au collisions at √(sNN) = 200 GeV for transverse momenta 1 (less-or-similar sign) pT (less-or-similar sign) 13 GeV/c are presented. Direct-photon yields at high pT scale as expected for particle production in hard processes. This supports jet-quenching models which attribute the suppression of high-pT hadrons to the energy loss of fast partons in the quark-gluon plasma. The low-pT direct-photon spectra, measured via e+e- pairs with small invariant masses, are possibly related to the production of thermal direct photons in Au+Au collisions at RHIC
