Electroweak corrections to lepton pair production in association with two hard jets at the LHC

TL;DR

This paper calculates next-to-leading order electroweak and QCD corrections for lepton pair production with two jets at the LHC, revealing significant effects in high-energy regions and angular distributions.

Contribution

It provides the first detailed NLO electroweak and QCD corrections for $pp o j j l^- l^+$ including off-shell effects at 13 TeV.

Findings

Per-cent-level total cross section corrections.

Significant distortions in high-energy tails due to electroweak Sudakov logarithms.

Deformations in angular distributions at a few percent level.

Abstract

We compute the next-to-leading order corrections of $O(\alpha_s^2\alpha^3)$ to the hadronic production of two oppositely charged leptons and two hard jets, $p p \to j j l^- l^+$, using Recola and Collier. We include electroweak and QCD corrections at the given order and all off-shell effects. We provide detailed predictions for the LHC operating at 13 TeV and obtain per-cent-level corrections for the total cross section. For differential distributions we find significant non-uniform distortions in high-energy tails at the level of several ten per cent due to electroweak Sudakov logarithms and deformations at the level of a few per cent for angular variables.
