Single-inclusive hadron production in transversely polarized p-p and pbar-p collisions with threshold resummation
Abstract
We investigate the resummation of large logarithmic perturbative corrections to the partonic cross sections for single-inclusive high-pT hadron production in collisions of transversely polarized hadrons. We perform the resummation to next-to-leading logarithmic accuracy. Phenomenological results are given for pbar-p collisions at center-of-mass energy of 14.5 GeV and for p-p collisions at 62.4 GeV and at 10 GeV, which are relevant for possible experiments at the GSI-FAIR, RHIC and J-PARC facilities, respectively. We find significant enhancements of the spin-dependent and spin-averaged cross sections, but a decrease of the double-spin asymmetry ATT.
