Next-to-leading Order QCD Corrections to A_TT for Single-Inclusive Hadron Production

Abstract

We report on a calculation of the next-to-leading order QCD corrections to the partonic cross sections contributing to single-inclusive high-p_T hadron production in collisions of transversely polarized hadrons. We give some predictions for the double spin asymmetry A_TT^\pi for the proposed experiments at RHIC and at the GSI.
