Qcd Prediction Of A(Tt) For Small Q(T) Dimuon Production In Pp And P(P)Over-Bar Collisions

We present QCD prediction of double-spin asymmetries (A(TT)) in transversely polarized Drell-Yan process at small transverse momentum Q(T) of dimuon. Resummation of large logarithmic corrections, relevant in small QT region, is performed up to next-to-leading logarithmic (NLL) accuracy A(TT) at RHIC, J-PARC and GSI are studied numerically in the corresponding kinematic regions. We show that the large A(TT) is obtained for small Q(T) and moderate energies.
