NNLO QCD corrections to lepton charge asymmetry in W decays at hadron colliders

We discuss the effect of next-to-next-to-leading order (NNLO) QCD corrections to the charged leptons asymmetry from W±boson decays in hadron collisions. The calculation includes the lepton kinematical cuts which are necessary applied in experimental analyses. We show some numerical results on the charge asymmetry in pp̄ collisions compared with the Tevatron data and in pp collisions at LHC energy.
