Soft-gluon resummation for high-pT inclusive-hadron production at COMPASS

We study the cross section for the photoproduction reaction γN→hX in fixed-target scattering at COMPASS, where the hadron h is produced at large transverse momentum. We investigate the role played by higher-order QCD corrections to the cross section. In particular we address large logarithmic "...
