Precision top-quark mass measurements at CDF
Original language description
We present a precision measurement of the top-quark mass using the full sample of Tevatron $/sqrt{s}=1.96$ TeV proton-antiproton collisions collected by the CDF II detector, corresponding to an integrated luminosity of 8.7 $fb^{-1}$. Using a sample of $t/bar{t}$ candidate events decaying into the lepton+jets channel, we obtain distributions of the top-quark masses and the invariant mass of two jets from the $W$ boson decays from data. We then compare these distributions to templates derived from signaland background samples to extract the top-quark mass and the energy scale of the calorimeter jets with {/it in situ} calibration. The likelihood fit of the templates from signal and background events to the data yields the single most-precise measurementof the top-quark mass, $/mtop = 172.85 $/pm$ 0.71 (stat) $/pm$ 0.85 (syst) GeV/c^{2}.
