1  AAD 2023S based on 140 fb${}^{-1}$ of data at 13 TeV. The second error is the sum of systematic effects ($\pm13$), luminosity ($\pm8$), and beam energy ($\pm2$) uncertainties. This measurement supersedes that of AAD 2020Q. The result is in good agreement with the NNLO+NNLL SM prediction.
2  TUMASYAN 2021J result is based on 137 fb${}^{-1}$ of data. The last uncertainty is due to the beam luminosity. The result is in agreement with the SM prediction of $832$ ${}^{+40}_{-46}$ pb at NNLO+NNLL. Measurements of differential and double-differential cross sections are also presented.
3  AAD 2020AH based on 139 fb${}^{-1}$ of data. The last quoted uncertainty is due to the beam luminosity. The result is for ${\mathit m}_{{{\mathit t}}}$ = 172.5 GeV and in agreement with the SM prediction of $832$ ${}^{+20}_{-29}$(scale)$\pm35(PDF+\alpha\mathrm {(s)}$) pb at NNLO+NNLL.
4  AAD 2020Q reports $826.4$ $\pm3.6$ $\pm11.5$ $\pm15.7$ $\pm1.9$ pb based on 36.1 fb${}^{-1}$ of data at 13 TeV. The four errors stem from statistics, systematic effects, luminosity, and beam energy, respectively. We have combined luminosity and beam energy uncertainties in quadrature. The result is in agreement with the SM prediction $832$ ${}^{+20}_{-29}$(scale)$\pm35(PDF+\alpha\mathrm {(s)}$) pb at NNLO+NNLL for ${\mathit m}_{{{\mathit t}}}$ = 172.5 GeV .
5  SIRUNYAN 2020V based on 35.9 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ data at $\sqrt {s }$ = 13 TeV. The last uncertainty is due to beam luminosity. The ${{\mathit t}}{{\overline{\mathit t}}}$ production cross section is measured in the ${{\mathit t}}$ ${{\overline{\mathit t}}}$ $\rightarrow$ ( ${{\mathit \ell}}{{\mathit \nu}_{{{{{\mathit \ell}}}}}}$) ( ${{\mathit \tau}_{{{h}}}}{{\mathit \nu}_{{{\tau}}}}$) ${{\mathit b}}{{\overline{\mathit b}}}$ final state, where ${{\mathit \tau}_{{{h}}}}$ refers to the hadronic decays of ${{\mathit \tau}}$. The result is for ${\mathit m}_{{{\mathit t}}}$ = 172.5 GeV and in agreement with the SM prediction at NNLO+NNLL.
6  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.
7  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.
8  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.
9  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.
10  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 $832$ ${}^{+20}_{-29}$(scale)$\pm35(PDF+\alpha\mathrm {(s)}$) pb at NNLO+NNLL for ${\mathit m}_{{{\mathit t}}}$ = 172.5 GeV .
11  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 $832$ ${}^{+20}_{-29}$(scale)$\pm35(PDF+\alpha\mathrm {(s)}$) pb at NNLO+NNLL.
