Resumen:
We calculate the next-to-leading order QCD corrections to the ‘‘direct’’ part of the spin-dependent cross section for single-inclusive charged-hadron photoproduction. This process could be studied experimentally in future polarized fixed-target lepton-nucleon experiments, but also at the DESY ep collider HERA after an upgrade to both beams being polarized. We present a brief numerical evaluation of our results by studying the K-factors and the scale dependence of the next-to-leading order cross section.
