W^+W^+jj at NLO in QCD: an exotic Standard Model signature at the LHC

TL;DR

This paper presents NLO QCD corrections to the $pp o W^+W^+jj$ process at the LHC, highlighting reduced theoretical uncertainties and the production of a hard third jet, which are crucial for identifying exotic Standard Model signatures.

Contribution

It provides the first detailed NLO QCD calculation for the $pp o W^+W^+jj$ process, improving predictions for this rare signature at the LHC.

Findings

NLO corrections reduce scale dependence of the cross-section.

A significant fraction of events feature a hard third jet.

The results enhance the understanding of exotic Standard Model signatures.

Abstract

The process $pp \to W^+W^+jj$ gives rise to an exotic Standard Model signature at the LHC, involving high-$p_{\perp}$ like-sign leptons, missing energy and jets. In this brief article the motivation for study, along with selected results from the computation of NLO QCD corrections to the QCD-mediated part of this process\cite{us} are presented. It is shown that the corrections reduce the dependence of the cross-section on renormalisation and factorisation scales, and produce a relatively hard third jet in a significant fraction of events.
