Rapidity Correlations and ΔG from Prompt Photon plus Jet Production in Polarized pp Collisions
Sanghyeon Chang, Claudio Coriano, L. E. Gordon
Abstract
A study of prompt photon plus associated jet production is performed at next-to-leading order (O(ααs2)) in QCD at S=200-500 GeV, appropriate for the RHIC polarized pp 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 ΔG is examined.
