The authors present the complete O({alpha}{sub s}{sup 2}) radiative corrections to the (non singlet) polarized Drell Yan cross section for the production of a lepton pair with a nonzero q{sub T}. The helicity of the incoming states is arbitrary. In the case of double photon, results for the longitudinal asymmetries and on the p{sub T} behavior of the cross section are also given (to O({alpha}{sub em}{sup 2}{alpha}{sub s})) in the central rapidity region of the tagged photon.
