Observation of electroweak W±Z boson pair production in association with two jets in pp collisions at s√= 13 TeV with the ATLAS detector Aaboud, M. Aguilar Saavedra, Juan Antonio Atlas Collaboration 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 36.1 fb−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 is measured to be σWZjj−EW=0.57+0.14−0.13(stat.)+0.07−0.06(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. 2020-03-05T09:10:45Z 2020-03-05T09:10:45Z 2019-05-13 info:eu-repo/semantics/article Álvarez Piqueras, D., Aparisi, P., Bailey, A.
