Next-to-leading order QCD corrections to one-hadron production in polarized pp collisions at BNL RHIC

We calculate the next-to-leading order (NLO) QCD corrections to the spin-dependent cross section for single-inclusive-hadron production in hadronic collisions. This process will be soon studied experimentally at the BNL Relativistic Heavy Ion Collider, providing a tool to unveil the polarized gluon...
