We complete our earlier study of the "direct" part of the cross section and spin asymmetry for the photoproduction process gamma N -> hX by analyzing the "resolved" contribution, for which the photon couples like a hadron through its parton structure. The incident photon and nucleon are longitudinally polarized and one observes a hadron h at high transverse momentum pT. Soft or collinear gluon emissions generate large logarithmic threshold corrections which we resum to next-to-leading logarithmic order. We compare our results with recent spin asymmetry data by the COMPASS Collaboration, highlighting the role of the fragmentation functions.
