The measurement uses the complete run 2 data set, corresponding to an integrated luminosity of 139 fb$^{-1}$, 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. The combined inclusive $t\\bar{t}$ charge asymmetry is measured as $A_\\text{C}^{t\\bar{t}} = 0.0068 \\pm 0.0015$, which differs from zero by 4.7~standard deviations. Differential measurements are performed as a function of the invariant mass, transverse momentum and longitudinal boost of the $t\\bar{t}$ system. Both inclusive and differential measurements are found to be compatible with the Standard Model predictions, at next-to-next-to-leading order in quantum chromodynamics perturbation theory with next-to-leading-order electroweak corrections.The measurements are interpreted in the framework of the Standard Model effective field theory, deriving competitive bounds on several Wilson coefficients.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.132116.v2/t1","@type":"Dataset","description":"- - - - - - - - Overview of HEPData Record - - - - - - - -...","name":"Table of contents"},{"@id":"https://doi.org/10.17182/hepdata.132116.v2/t2","@type":"Dataset","description":"The unfolded inclusive charge asymmetry.
