Photon production in √sNN=200 GeV Au+Au collisions measured by the PHENIX experiment at RHIC

الأصل · EN

Direct photon production in Au+Au collisions at √sNN=200 GeV has been measured in the pₜ range of 1<pₜ<5 GeV/c. The yield as acfunction of centrality is in agreement with published data of the RHIC 2002 run, and with results from a new method that explores very low mass dileptons. The result is compared to several theoretical calculations, and it is found that the measurement is not inconsistent with calculations including thermal photon contributions.
