NLO QCD Corrections to A_LL^pi

Abstract

We present a calculation for single-inclusive large-p_T pion production in longitudinally polarized pp collisions in next-to-leading order QCD. The corresponding double-spin asymmetry A_LL^pi for this process will soon be used at BNL-RHIC to measure Delta g.
