Measuring Bremsstrahlung Photons in 200 GeV p+p Collisions

Abstract
Direct photon production is an important observable in heavy ion collisions as photons are penetrating and therefore largely insensetive to final state effects that lead to jet quenching. Measurements of the fragmentation component to prompt photon yields in p+p and Au+Au collisions will provide both an important test of pQCD predictions and of predictions for modifications of this component in heavy ion collisions. By selecting photons associated with jets on the near side using hadron-photon correlations, fragmentation photons can be measured directly.
