Measurement of the tt¯ production cross section in pp collisions at s√=8 TeV in dilepton final states containing one τ lepton. Physics Letters B, 739:23-43.
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 tt¯→(ℓνℓ)(τντ)bb¯ , 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 s=8 TeV . The measured cross section σtt¯=257±3 (stat)±24 (syst)±7 (lumi) pb , assuming a top-quark mass of 172.5 GeV, is consistent with the standard model prediction.
