| 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 p T EMPTY > 30 GeV, where the leading jet has p T EMPTY > 500 GeV. The angular separation between the lepton and the closest jet with p T EMPTY > 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 fixed-order calculation of the W + 1 -jet process computed at next-to-next-to-leading order in the strong coupling constant.
