TMDs and polarized Drell-Yan process Jian Zhou LBNL In this talk, I will discuss the spin-dependent quark distributions at large transverse momentum. We derive their transverse momentum dependent behaviors in the collinear factorization approach. We further calculate the angular distribution of the Drell-Yan lepton pair production with polarized beams and present the results in terms of the collinear twist-3 correlation functions. In the intermediate transverse momentum region, our explicit calculations have shown that the collinear factorization and the transverse momentum dependent factorization approaches are consistent in the description of the lepton pair angular distributions.
