Prompt Photon Production in Polarized Hadron Collisions
Abstract
We consider spin asymmetries for prompt photon production in collisions of longitudinally polarized hadrons. This reaction will be a key tool at the BNL-RHIC pp collider for determining the gluon spin density in a polarized proton. We study the effects of QCD corrections, such as all-order soft-gluon `threshold' resummations.
