Charge asymmetry in top-pair production with the ATLAS detector

Measurement of the inclusive and differential top-quark charge asymmetry is carried out using full Run2 data from proton-proton collisions at center-of-mass energy of $13$ TeV collected by the ATLAS detector. Single-lepton and dilepton $t\bar t$ decay channel are combined. Distorting detector effects are removed using the fully Bayesian unfolding. In the dilepton decay channel, the leptonic charge asymmetry is determined. Results from the measurements are compared with the Standard Model prediction. The excess of charge asymmetry from zero charge-asymmetry hypothesis at the level of $4.7$ standard deviations is observed.
