Abstract

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 tt →(ℓν_ℓ)(τ_hν_τ)bb, (ℓ=e,μ). The data sample corresponds to an integrated luminosity of 2.0  fb^(-1) for the electron channel and 2.2  fb^(-1) for the muon channel, collected by the CMS detector at the LHC. This is the first measurement of the tt cross section explicitly including τ leptons in proton-proton collisions at √s=7  TeV. The measured value σ_(tt) =143±14(stat)±22(syst)±3(lumi)  pb is consistent with the standard model predictions.
