Abstract :
The utility of prompt photon plus associated jet production for constraining the size and shape of the polarized gluon density of the proton ΔG is examined at s= 40 GeV, appropriate for the proposed HERA-N̄ polarized pp collider experiment. The calculation is performed at next-to-leading order (O(ααs2)) in QCD. The reliability of the predictions are examined in some detail.
