Multiplicity and pseudorapidity distributions of photons in Au+Au collisions at √sոո= 62.4 GeV

We present the first measurement of pseudorapidity distribution of photons in the region 2.3 <or = eta <or = 3.7 for different centralities in Au+Au collisions at square root of (S(NN)) = 62.4 GeV. We find that the photon yield scales with the number of participating nucleons at all collision centralities studied. The pseudorapidity distribution of photons, dominated by pi0 decays, has been compared to those of charged pions, photons, and inclusive charged particles from heavy-ion and nucleon-nucleon collisions at various energies. The photon production has been shown to be consistent with the energy and centrality independent limiting fragmentation scenario.
