Logarithmic corrections to the QCD component of same-sign W-pair production for vector boson scattering studies

We present the results of the first calculation of the logarithmic corrections to the QCD contribution to same-sign W-pair production, pp -> e(+/-)nu(e)mu(+/-)nu(mu)jj, for same-sign charged leptons. This includes all leading logarithmic contributions which scale as alpha(4)(W)alpha(2+k)(s) log(k) ((s) over cap /p(perpendicular to)(2)). 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 cuts. These select regions of phase space where logarithms in (s) over cap /p(perpendicular to)(2). 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.

Automated summary

The study presents the first calculation of logarithmic corrections to the QCD contribution to same-sign W-pair production, showing that while the cross sections may see only a small change, various distributions relevant for experimental studies are significantly affected. The process is important for investigating electroweak couplings, with QCD contributions usually suppressed through cuts that enhance certain regions of phase space with logarithmic scaling.
