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.Contribution to the proceedings of the ``8th International Workshop on Deep-Inelastic Scattering'' (DIS2000), April 2000, Liverpool, UK; 3 Pages, LaTeX, two figures as eps filesHigh Energy Physics - Phenomenologytext
