Next-to-leading order QCD corrections to the polarized hadroproduction of heavy flavors

By Ingo Bojak and Stratmann. Marco

Abstract

We present the complete next-to-leading order QCD corrections to the polarized hadroproduction of heavy flavors which soon will be studied experimentally in polarized pp collisions at the BNL Relativistic Heavy Ion Collider (RHIC) in order to constrain the polarized gluon density Deltag. It is demonstrated that the dependence on unphysical renormalization and factorization scales is strongly reduced beyond the leading order. The sensitivity of the charm quark spin asymmetry to Deltag is analyzed in some detail, including the limited detector acceptance for leptons from charm quark decays at the BNL RHIC
