Abstract

We present the results of the first calculation of the logarithmic corrections to the QCD contribution to same-sign W-pair production, pp→e±νeμ±νμjj, for same-sign charged leptons. This includes all leading logarithmic contributions which scale as α4Wα2+kslogk(s^/p2⊥). This process is important for the study of electroweak couplings and hence the QCD contributions are usually suppressed through a choice of Vector Boson Scattering (VBS) cuts. These select regions of phase space where logarithms in s^/p2⊥ are enhanced. While the logarithmic corrections lead to a small change for the cross sections, several distributions relevant for experimental studies are affected more significantly.
