Abstract
We compute the [] mixed and [] corrections to the production of an on-shell boson in hadronic collisions. We obtain them by profiting from the calculation of the pure QCD terms after taking the corresponding Abelian limits. Therefore, we extend the available knowledge up to complete next-to-next-to-leading-order precision in . We present explicit results for the perturbative coefficients and perform the phenomenological analysis at different collider energies with particular emphasis on the mixed corrections. We study the contribution from the different channels and discuss the scale dependence stabilization effect. We find that the contributions compete with the pure QCD NNLO ones under relevant kinematical conditions for the LHC, despite the fact that they are small, typically at the few per mille level.
