Direct top-quark decay width measurement in the tt¯ lepton + jets channel at √s =8 TeV with the ATLAS experiment
Original language description
This paper presents a direct measurement of the decay width of the top quark using tt¯ events in the lepton+jets final state. The data sample was collected by the ATLAS detector at the LHC in proton–proton collisions at a centre-of-mass energy of 8 TeV and corresponds to an integrated luminosity of 20.2 fb−1 . The decay width of the top quark is measured using a template fit to distributions of kinematic observables associated with the hadronically and semileptonically decaying top quarks. The result, Γt=1.76±0.33 (stat.) +0.79−0.68 (syst.) GeV for a top-quark mass of 172.5 GeV, is consistent with the prediction of the Standard Model.n
