QCD corrections to the longitudinally polarized Drell-Yan process Original Research Article

In this paper we calculate the O(αs) corrections to the χF and y distributions of lepton pairs produced in collisions of longitudinally polarized hadrons. The numerical importance of these corrections is studied and consequences for the extraction of the polarized sea-quark distributions from a measurement of the longitudinally polarized Drell-Yan cross section are discussed.
