Spin Dependent Drell Yan and Double Prompt Photon Production to NLO QCD

arXiv:hep-ph/9705247 · doi:10.1063/1.53676

Abstract

We present the complete $O (α_{s}^{2})$ 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 $O (α_{e m}^{2} α_{s})$ ) in the central rapidity region of the tagged photon.
