Measurement of the tt̅ production cross section in pp collisions at √s=7 TeV in dilepton final states containing a τ
The top quark pair production cross section is measured in dilepton events with one electron or muon, and one hadronically decaying τ lepton from the decay tt̅ →(ℓν[subscript ℓ])(τ[subscript h]ν[subscript τ])bb̅ , (ℓ=e,μ). The data sample corresponds to an integrated luminosity of 2.0 fb[superscrip...

| description | The top quark pair production cross section is measured in dilepton events with one electron or muon, and one hadronically decaying τ lepton from the decay tt̅ →(ℓν[subscript ℓ])(τ[subscript h]ν[subscript τ])bb̅ , (ℓ=e,μ). The data sample corresponds to an integrated luminosity of 2.0 fb[superscript -1] for the electron channel and 2.2 fb[superscript -1] for the muon channel, collected by the CMS detector at the LHC. This is the first measurement of the tt̅ cross section explicitly including τ leptons in proton-proton collisions at √s=7 TeV. The measured value σ[subscript tt̅] =143±14(stat)±22(syst)±3(lumi) pb is consistent with the standard model predictions. |
