Spin dependent drell-yan beyond leading order: non-singlet corrections to O({alpha}{sup 2 ovr sub s}.
We present parton-level analytical results for the next-to-leading order non-singlet virtual and real corrections to the Drell-Yan differential cross-section. The dependence of the differential cross section on the helicity of the initial state partons is shown explicitly (the spins of the final state partons are summed). The calculation is implemented in dimensional regularization within the {ovr MS} scheme and with the 't Hooft-Veltman prescriptions for the n-dimensional {gamma}{sub 5}. Both the polarized initial state and the unpolarized cross sections can be obtained from our result. Our unpolarized cross section agrees with the previous result of Ellis, Martinelli and Petronzio in the non-singlet sector.
