Transverse Double-Spin Asymmetries for Dimuon Production in pp Collisions

Abstract

We calculate the transverse double-spin asymmetry for the production of dimuons in pp collisions as function of the dimuon rapidity and mass to next-to-leading accuracy in the strong coupling. Predictions for BNL-RHIC and HERA-N are made by assuming a saturation of Soffer's inequality at a low hadronic input scale. It seems unlikely that transversity can be measured in dimuon production at RHIC.
