Charged current Drell-Yan production at N3LO
Claude Duhr, Falko Dulat, Bernhard Mistlberger
Abstract
A bstract We present the production cross section for a lepton-neutrino pair at the Large Hadron Collider computed at next-to-next-to-next-to-leading order (N 3 LO) in QCD perturbation theory. We compute the partonic coefficient functions of a virtual W ± boson at this order. We then use these analytic functions to study the progression of the perturbative series in different observables. In particular, we investigate the impact of the newly obtained corrections on the inclusive production cross section of W ± bosons, as well as on the ratios of the production cross sections for W + , W − and/or a virtual photon. Finally, we present N 3 LO predictions for the charge asymmetry at the LHC.
