Measurement of the W⁺ W⁻ production cross section in pp collisions at a centre-of-mass energy of√ s= 13 TeV with the ATLAS experiment. Physics letters. B, 773, 354-374.https://hdl.handle.net/1808/27210The production of opposite-charge W-boson pairs in proton–proton collisions at √s=13TeV is measured using data corresponding to 3.16fb−1of integrated luminosity collected by the ATLAS detector at the CERN Large Hadron Collider in 2015. Candidate W-boson pairs are selected by identifying their leptonic decays into an electron, a muon and neutrinos. Events with reconstructed jets are not included in the candidate event sample. The cross-section measurement is performed in a fiducial phase space close to the experimental acceptance and is compared to theoretical predictions. Agreement is found between the measurement and the most accurate calculations available.© 2017 The Author. Published by Elsevier B.V.
