Direct- and Resolved-Photon Threshold Resummation for Polarized High-$p_T$ Hadron Production at COMPASS

Claudia Uebler, Andreas Schäfer, Werner Vogelsang

We complete our earlier study of the "direct" part of the cross section and spin asymmetry for the photoproduction process $\gamma N\to hX$ by analysing the "resolved" contribut…
