Abstract
After a brief recap of Transversity it is noted that Drell-Yan unpolarized processes display large azimuthal asymmetries. One such asymmetry, cos(2φ), is directly related to the leading twist transversity distribution h⊥1(x, kT). We use a model developed for semi-inclusive deep inelastic scattering that determines the Sivers function f⊥1T(x, kT) to predict the Drell-Yan asymmetry v as a function of q2, qT and x. The resulting predictions include a non-leading twist contribution from spin-averaged distributions that measurably effect lower energy results.
