Threshold resummation for polarized high-$p_T$ hadron production at COMPASS

We study the cross section for the photoproduction process g N ! hX where the incident photon and nucleon are longitudinally polarized and a hadron h is observed at high transverse momentum. Specifically, we address the “direct” part of the cross section, for which the photon interacts in a pointlik...

description We study the cross section for the photoproduction process g N ! hX where the incident photon and nucleon are longitudinally polarized and a hadron h is observed at high transverse momentum. Specifically, we address the “direct” part of the cross section, for which the photon interacts in a pointlike way. For this contribution we perform an all-order resummation of logarithmic threshold corrections generated by soft or collinear gluon emission to next-to-leading logarithmic accuracy. We present phenomenological results relevant for the COMPASS experiment and compare to recent COMPASS data
