Search for leptonic charge asymmetry in tt¯W production in final states with three leptons at √s = 13 TeV
Original language description
A search for the leptonic charge asymmetry (AcℓAcℓ) of top-quark-antiquark pair production in association with a W boson (tt‾WttW) is presented. The search is performed using final states with exactly three charged light leptons (electrons or muons) and is based on ss = 13 TeV proton-proton collision data collected with the ATLAS detector at the Large Hadron Collider at CERN during the years 2015–2018, corresponding to an integrated luminosity of 139 fb−1−1. A profile-likelihood fit to the event yields in multiple regions corresponding to positive and negative differences between the pseudorapidities of the charged leptons from top-quark and top-antiquark decays is used to extract the charge asymmetry. At reconstruction level, the asymmetry is found to be −0.12 ± 0.14 (stat.) ± 0.05 (syst.).
