Direct Photon Production in p+p and d+Au Collisions Measured with the PHENIX Experiment Original Research Article

Direct photon yield measured in p+p and d+Au collisions at View the MathML source with the PHENIX experiment is presented and compared to pQCD predictions. In the case of p+p collisions both the inclusive and isolated direct photon production cross-sections are measured. Relative contribution of isolated direct photons is somewhat below but still agree within errors with pQCD predictions. In the case of d+Au collisions no modifications due to presence of cold matter are found within errors.
