Abstract

The top-quark pair production cross section is measured in final states with one electron or muon and one hadronically decaying τ lepton from the process t(t)over-bar -> (l ν_l) (τ ν_τ) b(b)over-bar, where l = e, μ. 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 σ_[t(t)over-bar] = 257 +/- 3(stat) +/- 24(syst) +/- 7(lumi) pb, assuming a top-quark mass of 172.5 GeV, is consistent with the standard model prediction.
