Measurements of Photon and π 0 Production in Heavy Ion Collisions at RHIC

Abstract

Inclusive transverse momentum spectra of photons and π 0 s about mid–rapidity are presented for 197 Au+ 197 Au collisions at √ s NN = 130 GeV. Photon pair conversions have been reconstructed from charged tracks measured with the central Time Projection Chamber (TPC) of STAR. Contributions of the π 0 → γγ decay in the inclusive photon spectra have been… (More)
