Observation of electroweak W ± Z boson pair production in association with two jets in pp collisions at s=13 TeV with the ATLAS detector
Author
Summary, in English
An observation of electroweak W ± Z production in association with two jets in proton–proton collisions is presented. The data collected by the ATLAS detector at the Large Hadron Collider in 2015 and 2016 at a centre-of-mass energy of s=13 TeV are used, corresponding to an integrated luminosity of 36.1fb −1 . Events containing three identified leptons, either electrons or muons, and two jets are selected. The electroweak production of W ± Z bosons in association with two jets is measured with an observed significance of 5.3 standard deviations. A fiducial cross-section for electroweak production including interference effects and for a single leptonic decay mode is measured to be σ WZjj−EW =0.57 −0.13 +0.14 (stat.) −0.06 +0.07 (syst.)fb. Total and differential fiducial cross-sections of the sum of W ± Zjj electroweak and strong productions for several kinematic observables are also measured. © 2019 The Author(s)
