High-energy logarithmic corrections to the QCD component of same-sign W-pair production

Abstract

We describe the calculation of the QCD contribution to same-sign WW-pair production, pp\to e^\pm \nu_e \mu^\pm \nu_\mu jjpp→e±νeμ±νμjj, resumming all contributions scaling as \alpha_W^4 \alpha_s^{2+k}\log^k(\hat s/p_\perp^2)αW4αs2+klogk(ŝ/p⊥2)~. These leading logarithmic contributions are enhanced by typical cuts used for Vector Boson Scattering (VBS) studies. We show that while the cross sections are little affected by these corrections, other more exclusive observables relevant for experimental studies are affected more significantly.
