Abstract

We describe the calculation of the QCD contribution to same-sign W-pair production, pp→ e^± ν_e μ^± ν_μjj, resumming all contributions scaling as α_W⁴ α_s^2+klog^k( s/p_⊥²) [arXiv:2107.06818]. 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.
