Electroweak NLO corrections to Wγ production at the LHC — •Christian Pasold and Ansgar Denner — Julius-Maximilians-Universität, Würzburg, Deutschland

We present a full calculation of electroweak NLO corrections to Wγ production including leptonic decays of the W boson. We take into account photon-induced contributions leading to singularities from photons inside jets. These are treated with the quark-to-photon fragmentation function. We discuss the numerical results for the total cross section and several distributions as well as the effects of non-collinear-safe final-state radiation of light fermions. In some areas of the phase space the electroweak NLO corrections amount up to ∼20 % of the leading-order cross section.
