1  AAD 2023BA is based on 139 fb${}^{-1}$ of data. Inclusive ${{\mathit t}}{{\overline{\mathit t}}}$ charge asymmetry is measured to be nonzero with 4.7$\sigma $ significance. Also differential ${{\mathit t}}{{\overline{\mathit t}}}$ as well as lepton charge asymmetries are measured. All the results are consistent with the SM predictions which include NNLO QCD + NLO EW corrections.
2  TUMASYAN 2023BD is based on 138 fb${}^{-1}$ of data. ${{\mathit t}}{{\overline{\mathit t}}}$ charge asymmetry for highly Lorentz-boosted top quarks is measured and is in agreement with the NNLO QCD + NLO EW corrected SM prediction of $0.94$ ${}^{+0.05}_{-0.07}\%$. The event selection is optimized for highly-boosted top quarks.
