Abstract
We present a calculation for single-inclusive large-p(T) pion production in longitudinally polarized pp collisions in next-to-leading order QCD. We choose an approach where fully analytical expressions for the underlying partonic hard-scattering cross sections are obtained. We simultaneously rederive the corresponding corrections to unpolarized scattering and confirm the results existing in the literature. Our results allow to calculate the double-spin asymmetry A(LL)(pi) for this process at next-to-leading order, which will soon be used at the BNL Relativistic Heavy Ion Collider to measure the polarization of gluons in the nucleon.
