The search is performed using final states with exactly three charged light leptons (electrons or muons) and is based on $\\sqrt{s} = 13$ 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}$. 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 $-0.123 \\pm 0.136$ (stat.) $\\pm \\, 0.051$ (syst.). An unfolding procedure is applied to convert the result at reconstruction level into a charge-asymmetry value in a fiducial volume at particle level with the result of $-0.112 \\pm 0.170$ (stat.) $\\pm \\, 0.054$ (syst.). The Standard Model expectations for these two observables are calculated using Monte Carlo simulations with next-to-leading-order plus parton shower precision in quantum chromodynamics and including next-to-leading-order electroweak corrections. They are $-0.084 \\, ^{+0.005}_{-0.003}$ (scale) $\\pm\\, 0.006$ (MC stat.) and $-0.063 \\, ^{+0.007}_{-0.004}$ (scale) $\\pm\\, 0.004$ (MC stat.) respectively, and in agreement with the measurements.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.140938.v1/t1","@type":"Dataset","description":"Measured values of the leptonic charge asymmetry ($A_c^{\\ell}$) in ttW production in the three lepton channel.
