Inclusive and differential measurements of the top–antitop (tt‾tt) charge asymmetry ACtt‾ACtt​ and the leptonic asymmetry ACℓℓ‾ACℓℓ​ are presented in proton–proton collisions at √s ​ = 13 TeV recorded by the ATLAS experiment at the CERN Large Hadron Collider. The measurement uses the complete Run 2 dataset, corresponding to an integrated luminosity of 139 fb−1−1, combines data in the single-lepton and dilepton channels, and employs reconstruction techniques adapted to both the resolved and boosted topologies. A Bayesian unfolding procedure is performed to correct for detector resolution and acceptance effects.
