  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
ttbar to (l nu[l]) (tau nu[tau]) bbbar, where l = e, mu. The data sample
corresponds to an integrated luminosity of 19.6 inverse femtobarns collected
with the CMS detector in proton-proton collisions at sqrt(s) = 8 TeV. The
measured cross section sigma[ttbar] = 257 +/- 3 (stat) +/- 24 (syst) +/- 7
(lumi) pb, assuming a top-quark mass of 172.5 GeV, is consistent with the
standard model prediction.
