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

TL;DR

This paper calculates high-energy QCD logarithmic corrections to same-sign W-pair production, showing that while total cross sections are minimally affected, certain exclusive observables relevant for experiments are significantly influenced.

Contribution

It introduces a resummation of all leading logarithmic contributions to the QCD component of same-sign W-pair production, enhancing the understanding of these corrections in VBS analyses.

Findings

Cross sections are minimally affected by the corrections.

Exclusive observables relevant for experiments are significantly influenced.

Resummation improves theoretical predictions for VBS processes.

Abstract

We describe the calculation of the QCD contribution to same-sign $W$-pair production, $pp\to e^\pm \nu_e \mu^\pm \nu_\mu jj$, resumming all contributions scaling as $\alpha_W^4 \alpha_s^{2+k}\log^k(\hat s/p_\perp^2)$ [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.
