Description

Drell-Yan processes allow to fully explore the partonic structure of hadrons due to the presence of a purely leptonic final state. Thus, Transverse Momentum Dependent distributions (TMD's), like the Sivers and the Boer-Mulders functions and the Transversity distribution, can be directly accessed. A formal expression for the cross section of the unpolarized and single polarized Drell-Yan (DY) processes including TMD's is presented. Using our latest extraction of the Sivers functions from a fit on SIDIS data, we give some estimations of the Sivers effect in DY processes.
