W+n-jet predictions at the Large Hadron Collider at next-to-leading order matched with a parton shower

TL;DR

This paper presents the first detailed predictions for W-boson production with up to three jets at the LHC, combining next-to-leading order QCD calculations with parton shower simulations and comparing them to experimental data.

Contribution

It introduces a novel computation of differential cross sections for W+jets at NLO matched with parton showers, enhancing accuracy in theoretical predictions.

Findings

Good agreement with LHC data for W+jets production

Improved theoretical precision over previous models

First NLO+PS predictions for up to three jets

Abstract

For the first time, differential cross sections for the production of W-bosons in conjunction with up to three jets, computed at next-to leading order in QCD and including parton shower corrections, are presented and compared to recent experimental data from the Large Hadron Collider.
