Hard Photons and Neutral Pions from RHIC

Abstract

In order to fix the parameters for predictions of hard photon and pion production in $Au+Au$ collisions at $\sqrt{s}=200$ GeV, proton-proton and proton-nucleus data are analyzed in perturbative QCD in the energy range $\sqrt{s}\approx 20-60$ GeV and a prediction at RHIC energy is given.
