Abstract

A study of prompt photon plus associated jet production is performed at next-to-leading order (O( $\alpha\alpha_s^2$ )) in QCD at $\sqrt{S}=200-500$ GeV, appropriate for the RHIC polarized $\vec{p}\vec{p}$ collider experiment. Momentum correlations between the jet and photon are examined and the utility of the process as a method for constraining the size and shape of the polarized gluon density of the proton $\Delta G$ is examined.
