Single-inclusive hadron production in transversely polarized pp and p̄p collisions with threshold resummation

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...
