Partons and QCD in high-energy polarized pp collisions

Abstract

We present and use a technique for implementing in a fast way, and without any approximations, higher-order calculations of partonic cross sections into global analyses of parton distribution functions. The approach, which is set up in Mellin-moment space, is particularly suited for analyses of future data from polarized proton-proton collisions at RHIC, but not limited to this case. We also briefly discuss the effects of soft-gluon resummations on spin asymmetries.Comment: 6 pages, LaTeX, 5 eps figures, Invited talk presented by W.
