1  KHACHATRYAN 2017B based on 5.0 fb${}^{-1}$ of data, using a binned likelihood fit of templates to the data. Also the ratio ${\mathit \sigma (}$ ${{\mathit t}}{{\overline{\mathit t}}}$ ; 8 TeV${)}/{\mathit \sigma (}$ ${{\mathit t}}{{\overline{\mathit t}}}$ ; 7 TeV${)}$ = $1.43$ $\pm0.04$ $\pm0.07$ $\pm0.05$ is reported. The results are in agreement with NNLO SM predictions.
2  KHACHATRYAN 2016AW based on 5.0 fb${}^{-1}$ of data, using a binned likelihood fit to differential distributions of ${{\mathit b}}$-tagged and non-${{\mathit b}}$-tagged jets. The result is in good agreement with NNLO SM predictions.
3  Based on 4.6 fb${}^{-1}$ of data. Uses a template fit to distributions of $\not E_T$ and jet multiplicities to measure simultaneously ${{\mathit t}}{{\overline{\mathit t}}}$ , ${{\mathit W}}{{\mathit W}}$ , and ${{\mathit Z}}$/ ${{\mathit \gamma}^{*}}$ $\rightarrow$ ${{\mathit \tau}}{{\mathit \tau}}$ cross sections, assuming ${\mathit m}_{{{\mathit t}}}$ = 172.5 GeV.
4  AAD 2015CC based on 4.6 fb${}^{-1}$ of data. The event selection criteria are optimized for the ${{\mathit \ell}}{{\mathit \tau}_{{h}}}$ + jets channel. Using only this channel $183$ $\pm9$ $\pm23$ $\pm3$ pb is derived for the cross section.
5  AAIJ 2015R, based on 1.0 fb${}^{-1}$ of data, reports $0.239$ $\pm0.053$ $\pm0.033$ $\pm0.024$ pb cross section for the forward fiducial region ${{\mathit p}_{{T}}}({{\mathit \mu}}$) $>$ 25 GeV, 2.0 $<$ ${{\mathit \eta}}({{\mathit \mu}}$) $<$ 4.5, 50 GeV $<$ ${{\mathit p}_{{T}}}$ (${{\mathit b}}$) $<$ 100 GeV, 2.2 $<$ ${{\mathit \eta}}({{\mathit b}}$) $<$ 4.2, ${{\mathit \Delta}}{{\mathit R}}({{\mathit \mu}},{{\mathit b}}$) $>$ 0.5, and ${{\mathit p}_{{T}}}({{\mathit \mu}}+{{\mathit b}}$) $>$ 20 GeV. The three errors are from statistics, systematics, and theory. The result agrees with the SM NLO prediction.
6  AAD 2014AY reports $182.9$ $\pm3.1$ $\pm4.2$ $\pm3.6$ $\pm3.3$ pb value based on 4.6 fb${}^{-1}$ of data. The four errors are from statistics, systematic, luminosity, and the 0.66$\%$ beam energy uncertainty. We have combined the systematic uncertainties in quadrature. The result is for ${\mathit m}_{{{\mathit t}}}$ = 172.5GeV; for other ${\mathit m}_{{{\mathit t}}}$, ${\mathit \sigma (}{\mathit m}_{{{\mathit t}}}{)}$ = $\sigma $(172.5GeV)${\times }[1-0.0028{\times }({\mathit m}_{{{\mathit t}}}-172.5$GeV)]. The result is consistent with the SM prediction at NNLO.
7  Based on 1.67 fb${}^{-1}$ of data. The result uses the acceptance for ${\mathit m}_{{{\mathit t}}}$ = 172.5 GeV.
8  Based on 3.54 fb${}^{-1}$ of data.
9  Based on 2.3 fb${}^{-1}$ of data.
10  Based on 3.9 fb${}^{-1}$ of data.
11  Based on 35 pb${}^{-1}$ of data for an assumed top quark mass of ${\mathit m}_{{{\mathit t}}}$ = 172.5 GeV.
12  Based on 0.70 fb${}^{-1}$ of data. The 3 errors are from statistics, systematics, and luminosity. The result uses the acceptance for ${\mathit m}_{{{\mathit t}}}$ = 172.5 GeV.
13  Based on 35 pb${}^{-1}$ of data. The 3 errors are from statistics, systematics, and luminosity. The result uses the acceptance for ${\mathit m}_{{{\mathit t}}}$ = 172.5 GeV and $173$ $\pm17$ ${}^{+18}_{-16}$ $\pm6$ pb is found without the ${{\mathit b}}$-tag.
14  Based on 2.05 fb${}^{-1}$ of data. The hadronic ${{\mathit \tau}}$ candidates are selected using a BDT technique. The 3 errors are from statistics, systematics, and luminosity. The result uses the acceptance for ${\mathit m}_{{{\mathit t}}}$ = 172.5 GeV.
15  Based on 2.0 fb${}^{-1}$ and 2.2 fb${}^{-1}$ of data for ${{\mathit \ell}}$ = ${{\mathit e}}$ and ${{\mathit \ell}}$ = ${{\mathit \mu}}$, respectively. The 3 errors are from statistics, systematics, and luminosity. The result uses the acceptance for ${\mathit m}_{{{\mathit t}}}$ = 172.5 GeV.
16  Based on 2.3 fb${}^{-1}$ of data. The 3 errors are from statistics, systematics, and luminosity. The result uses the profile likelihood-ratio (PLB) method and an assumed ${\mathit m}_{{{\mathit t}}}$ of 172.5 GeV.
17  Based on 2.9 pb${}^{-1}$ of data. The result for single lepton channels is $142$ $\pm34$ ${}^{+50}_{-31}$ pb, while for the dilepton channels is $151$ ${}^{+78}_{-62}{}^{+37}_{-24}$ pb.
18  Result is based on 36 pb${}^{-1}$ of data. The first uncertainty corresponds to the statistical and systematic uncertainties, and the second corresponds to the luminosity.
19  Based on 36 pb${}^{-1}$ of data. The ratio of ${{\mathit t}}{{\overline{\mathit t}}}$ and ${{\mathit Z}}/{{\mathit \gamma}^{*}}$ cross sections is measured as ${\mathit \sigma (}$ ${{\mathit p}}$ ${{\mathit p}}$ $\rightarrow$ ${{\mathit t}}{{\overline{\mathit t}}}{)}/{\mathit \sigma (}$ ${{\mathit p}}$ ${{\mathit p}}$ $\rightarrow$ ${{\mathit Z}}$ / ${{\mathit \gamma}^{*}}$ $\rightarrow$ ${{\mathit e}^{+}}{{\mathit e}^{-}}$ / ${{\mathit \mu}^{+}}{{\mathit \mu}^{-}}{)}$ = $0.175$ $\pm0.018$(stat)$\pm0.015$(syst) for 60 $<$ ${\mathit m}_{\mathrm { {{\mathit \ell}} {{\mathit \ell}} }}<$ 120 GeV, for which they use an NNLO prediction for the denominator cross section of $972$ $\pm42$ pb.
20  Result is based on 36 pb${}^{-1}$ of data. The first error is from statistical and systematic uncertainties, and the second from luminosity. This is a combination of a measurement in the dilepton channel (CHATRCHYAN 2011F) and the measurement in the ${{\mathit \ell}}$ + jets channel (CHATRCHYAN 2011Z) which yields $150$ $\pm9$ $\pm17$ $\pm6$ pb.
21  Result is based on $3.1$ $\pm0.3$ pb${}^{-1}$ of data.
