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

TL;DR

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.

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.

• Figure 1: Transverse momentum of the first, second and third jet (from top to bottom) in $W^\pm+\geq 1,2,3$ jet production as measured by ATLAS Aad:2012en compared to predictions from the corresponding fixed order and MC@NLO simulations. The blue band display fixed-order uncertainties, the orange band shows resummation uncertainties.
• Figure 2: Angular correlations of the two leading jets in $W^\pm+\geq 2$ jet production as measured by ATLAS Aad:2012en compared to predictions from the $W^\pm+2$ jet fixed order and MC@NLO simulations. The blue band display fixed-order uncertainties, the orange band shows resummation uncertainties.
