Vogelsang %J Physics %D 1999 %I arXiv %R 10.1103/PhysRevD.60.117502 %X We calculate the rapidity dependence of the transverse double-spin asymmetry for the Drell-Yan process to next-to-leading order in the strong coupling. Input transversity distributions are obtained by saturating the Soffer inequality at a low hadronic mass scale. Results for the polarized BNL-RHIC proton-proton collider and the proposed HERA-N fixed-target experiment are presented, and the influence of the limited muon acceptance of the detectors on measurements of the asymmetry is studied in detail. %U http://arxiv.org/abs/hep-ph/9902250v2
