Direct measurement of the total decay width of the top quark

Abstract: We present a measurement of the total decay width of the top quark using events with top-antitop quark pair candidates reconstructed in the final state with one charged lepton and four or more hadronic jets. We use the full Tevatron run II data set of ?s=1.96 TeV proton-antiproton collisions recorded by the CDF II detector. The top quark mass and the mass of the hadronically decaying W boson are reconstructed for each event and compared with distributions derived from simulated signal and background samples to extract the top quark width (?top) and the energy scale of the calorimeter jets with in situ calibration. For a top quark mass M top=172.5 GeV/c2, we find 1.10
