Abstract

We present the complete $O(\alpha_s^2)$ radiative corrections to the (non singlet) polarized Drell Yan cross section for the production of a lepton pair with a nonzero $q_T$ . The helicity of the incoming states is arbitrary. In the case of double photon, results for the longitudinal asymmetries and on the $p_T$ behavior of the cross section are also given (to $O(\alpha_{em}^2\alpha_s )$ ) in the central rapidity region of the tagged photon.
