1  SIRUNYAN 2019AR based on 35.9 fb${}^{-1}$ of data. Obtained from the visible cross section measured using a template fit to multidifferential distributions categorized according to the ${{\mathit b}}$-tagged jet multiplicity. The result is for ${\mathit m}_{{{\mathit t}}}$ = 172.5 GeV and in agreement with the SM prediction at NNLO+NNLL.
2  SIRUNYAN 2019P reports differential ${{\mathit t}}{{\overline{\mathit t}}}$ cross sections measured using dilepton events at 13 TeV with 35.9 fb${}^{-1}$ and compared to NLO predictions.
3  KHACHATRYAN 2017N based on 2.2 fb${}^{-1}$ of data. The last quoted uncertainty is due to the beam luminosity. This measurement supersedes that of KHACHATRYAN 2016J.
4  SIRUNYAN 2017W based on 2.2 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ data at $\sqrt {s }$ = 13 TeV. Events are categorized according to the jet multiplicity and the number of ${{\mathit b}}$-tagged jets. A likelihood fit is performed to the event distributions to compare to the NNLO+NNLL prediction.
5  AABOUD 2016R reported value $818$ $\pm8$ $\pm27$ $\pm19$ $\pm12$ pb based on 3.2 fb${}^{-1}$ of data. The four errors are from statistics, systematic, luminosity, and beam energy. We have combined the systematic uncertainties in quadrature. The result is in agreement with the SM prediction $832$ ${}^{+40}_{-46}$ pb at NNLO+NNLL for ${\mathit m}_{{{\mathit t}}}$ = 172.5 GeV .
6  KHACHATRYAN 2016J based on 43 pb${}^{-1}$ of data. The last uncertainty is due to luminosity. The result is for ${\mathit m}_{{{\mathit t}}}$ = 172.5 GeV and in agreement with the SM prediction $832$ ${}^{+40}_{-46}$ pb at NNLO+NNLL.
