We present the next-to-next-to-leading order (NNLO) QCD computation of the charged leptons asymmetry from W± boson decays in hadron collisions. Our calculation includes the dependence on the lepton kinematical cuts applied in actual experimental analyses. We compare numerical results on the charge asymmetry in pp¯ collisions with some of the available Tevatron data. We show illustrative results for the asymmetry in pp collisions at LHC energy.

Abstract
We present the next-to-next-to-leading order (NNLO) QCD computation of the charged leptons asymmetry from W± boson decays in hadron collisions. Our calculation includes the dependence on the lepton kinematical cuts applied in actual experimental analyses. We compare numerical results on the charge asymmetry in pp¯ collisions with some of the available Tevatron data. We show illustrative results for the asymmetry in pp collisions at LHC energy.
