Abstract: The top-quark pair production cross section is measured in final states with one electron or muon and one hadronically decaying $\tau$ lepton from the process $\mathrm{ t \bar{t} }$ to $(\ell\nu_\ell) (\tau\nu_\tau) \mathrm { b \bar{b} }$ , where $\ell = \mathrm{ e }$ , $\mu$ . The data sample corresponds to an integrated luminosity of 19.6 fb $^{-1}$ collected with the CMS detector in proton-proton collisions at $\sqrt{s}$ = 8 TeV. The measured cross section $\sigma_{ \mathrm{ t \bar{t} } }$ = 257 $\pm$ 3 (stat) $\pm$ 24 (syst) $\pm$ 7 (lumi) pb, assuming a top-quark mass of 172.5 GeV, is consistent with the standard model prediction.
