Measurement of prompt photon in sqrt(s)=200GeV pp collisions

Abstract

This report presents the preliminary result for the prompt photon production cross section in proton-proton collisions in the mid-rapidity region using the PHENIX detector. The NLO pQCD calculation is in good agreement with the data. The measurement was made with and without an isolation cut. The isolation cut significantly improves the signal purity without reducing the signal yield. This is an important step for the future spin asymmetry measurement.
