Direct photon production is an important observable in heavy ion collisions, as photons are penetrating and therefore largely insensitive to final state effects. Measurements of the fragmentation component of direct photon yields in p + p and Au + Au collisions will provide important tests of pQCD predictions and of predictions for modifications of this component in heavy ion collisions. By selecting photons associated with jets on the same side using hadron-photon correlations, fragmentation photons can be measured directly.
