1  AAD 2024AN based on 140 fb${}^{-1}$ of data. The result is consistent with the NLO+NNLL SM prediction including EW corrections of $0.863$ ${}^{+0.073}_{-0.085}$(scale)$~\pm0.028$(PDF + ${{\mathit \alpha}_{{{s}}}}$) pb. Also overall the differential cross sections are in good agreement with the SM predictions. All hadronic decays of ${{\mathit t}}{{\overline{\mathit t}}}$ are also included.
2  AAD 2021AS based on 139 fb${}^{-1}$ of data. The result is consistent with the SM prediction of $0.88$ ${}^{+0.09}_{-0.10}$ pb which includes NLO QCD+EW corrections. Also overall the differential cross sections are in good agreement with the SM predictions.
3  Superseded by AAD 2024AN
4  SIRUNYAN 2020AB based on 77.5 fb${}^{-1}$ of data at 13 TeV. The result is consistent with the NLO SM prediction of $0.84$ $\pm0.10$ pb. Differential cross sections are measured and used to constrain the anomalous couplings and Wilson coefficients for the ${{\mathit t}}{{\overline{\mathit t}}}{{\mathit Z}}$ interaction.
5  AABOUD 2019AR based on 35.9 fb${}^{-1}$ of data. ${{\mathit t}}{{\overline{\mathit t}}}{{\mathit W}}$ and ${{\mathit t}}{{\overline{\mathit t}}}{{\mathit Z}}$ cross sections are simultaneously measured using a combined fit to the events divided into multiple regions. The result is consistent with the SM prediction at NLO $0.88$ ${}^{+0.09}_{-0.11}$ pb. It is also used to constrain the Wilson coefficients for dimension-six operators which modify the ${{\mathit t}}{{\overline{\mathit t}}}{{\mathit Z}}$ vertex.
6  Based on 35.9 fb${}^{-1}$ of proton-proton data taken at $\sqrt {s }$ = 13 TeV. The result is consistent with the SM prediction and is used to constrain the Wilson coefficients for dimension-six operators describing new interactions. The result is consistent with the SM prediction at NLO $0.839$ $\pm0.101$ pb.
