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 $O(α_{em}^2α_s )$) in the central rapidity region of the tagged photon.
