Logarithmic corrections to the QCD component of same-sign W-pair production for VBS studies

High Energy Physics - Phenomenology 2022-05-19 v2

Abstract

We present the results of the first calculation of the logarithmic corrections to the QCD contribution to same-sign WW-pair production, ppe±νeμ±νμjjpp\to e^\pm \nu_e \mu^\pm \nu_\mu jj, for same-sign charged leptons. This includes all leading logarithmic contributions which scale as αW4αs2+klogk(s^/p2)\alpha_W^4 \alpha_s^{2+k}\log^k(\hat s/p_\perp^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 (VBS) cuts. These select regions of phase space where logarithms in s^/p2\hat s/p_\perp^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.
