Abstract:	摘要： 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. 出版者： Elsevier B.V 出版日期： 2014-12-12 出處： Physics letters.
