| Abstract: The cross section of the top quark pair production process $\mathrm{t\overline{t}}\rightarrow (\ell\nu_{\ell})(\tau_{\mathrm{h}}\nu_{\tau})\mathrm{b\overline{b}}$ is measured, where the $\tau_{\mathrm{h}}$ refers to the hadronic decays of the $\tau$ lepton, and $\ell=$ e, $\mu$. The data sample corresponds to an integrated luminosity of 35.9 fb$^{-1}$ and was collected in 2016 by the CMS detector in proton-proton collisions at $\sqrt{s}= $ 13 TeV. The measured cross section is $\sigma_{\mathrm{t\overline{t}}} = $ 781 $\pm$ 7 (stat) $\pm$ 62 (syst) $\pm$ 20 (lumi) pb. The ratio of the partial width $\Gamma(\mathrm{t}\rightarrow\tau\nu_{\tau}\mathrm{b})$ to the total width is measured to be 0.1050 $\pm$ 0.0009 (stat) $\pm$ 0.0071 (syst). | ||
