A set of measurements for the production of a W-boson in association with high-transverse-momentum jets is presented using 140 fb−1 of proton–proton collision data at a centre-of-mass energy of √s = 13 TeV collected by the ATLAS detector at the LHC. The measurements are performed in final states in which the W-boson decays into an electron or muon plus a neutrino and is produced in association with jets with pT > 30 GeV, where the leading jet has pT > 500 GeV. The angular separation between the lepton and the closest jet with pT > 100 GeV is measured and used to define a collinear phase space, wherein measurements of kinematic properties of the W-boson and the associated jet are performed. The collinear phase space is populated by dijet events radiating a W-boson and events with a W-boson produced in association with several jets and it serves as an excellent data sample to probe higher-order theoretical predictions. Measured differential distributions are compared with predictions from state-of-the-art next-to-leading order multi-leg merged Monte Carlo event generators and a fixedorder calculation of the W +1-jet process computed at nextto-next-to-leading order in the strong coupling constant.

Abstract

A set of measurements for the production of a W-boson in association with high-transverse-momentum jets is presented using 140 fb−1 of proton–proton collision data at a centre-of-mass energy of √s = 13 TeV collected by the ATLAS detector at the LHC. The measurements are performed in final states in which the W-boson decays into an electron or muon plus a neutrino and is produced in association with jets with pT > 30 GeV, where the leading jet has pT > 500 GeV. The angular separation between the lepton and the closest jet with pT > 100 GeV is measured and used to define a collinear phase space, wherein measurements of kinematic properties of the W-boson and the associated jet are performed. The collinear phase space is populated by dijet events radiating a W-boson and events with a W-boson produced in association with several jets and it serves as an excellent data sample to probe higher-order theoretical predictions. Measured differential distributions are compared with predictions from state-of-the-art next-to-leading order multi-leg merged Monte Carlo event generators and a fixedorder calculation of the W +1-jet process computed at nextto-next-to-leading order in the strong coupling constant.
