Abstract: (arXiv)

We present a calculation of the two-loop splitting functions for the evolution of the twist-2 `transversity' parton densities of transversely polarized nucleons. We study the implications of our results for Soffer's inequality for the case of valence quark densities.

p p: inclusive reaction
polarization: transverse
Drell-Yan process
muon: pair production
momentum spectrum: parton
quantum chromodynamics
perturbation theory: higher-order
effect: higher-twist
Mellin transformation
