Abstract

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 ...
