We report on recent measurements of the top quark mass using t{bar t} candidate events selected in {approx_equal} 320 pb{sup -1} of data from the ''Run II'' operation period of the Tevatron p{bar p} collider. More emphasis is given on the best single measurement to date (M{sub top} = 173.5{sub -3.8}{sup +3.9} GeV/c{sup 2}), provided by CDF using the ''lepton plus jets'' channel, where one W decays to a lepton-neutrino pair and the other into quarks (top quarks decay to Wb almost 100% of the time).

We present the measurement of the top quark mass using L = 110 pb−1 data sample of p{ovr p} collisions at (square root)s = 1.8 TeV collected with the Collider Detector at Fermilab (CDF). We show the results for the different channels and discuss with some emphasis the determination of the systematic uncertainties. 7 refs., 10 figs., 5 tabs.

Download Top Quark Mass Measurement at CDF Run-II. Book in PDF, ePub and Kindle
CDF has resumed the top quark mass measurement with upgraded detectors and Tevatron complex. High statistics should allow us to determine the top mass with an uncertainty of a few GeV/c2 by the end of Run II. The current measured value, using an integrated luminosity of (almost equal to) 108 pb−1, is 177.5{sub -9.4}{sup +12.7} (stat.) " 7.1(syst.) GeV/c2 (lepton + jets with one b-jet tagged mode: the current best mode), which is consistent with RunI measurements.

Download Measurement of the W Boson and Top Quark Masses at CDF. Book in PDF, ePub and Kindle
We report on the measurements of the W boson and top-quark masses with the CDF II detector in p{bar p} collisions at {radical}s = 1.96 TeV at the Fermilab Tevatron. We highlight the major features and uncertainties for the W mass measurement. The top-quark mass measurements are presented in each t{bar t} decay channels. The combination of the most precise measurements from CDF to date leads to M{sub top} = 172.4 {+-} 1.5(stat.) {+-} 2.2(sys.) GeV/c{sup 2}, corresponding to a relative uncertainty of 1.5%.

Download Precision Top-Quark Mass Measurements at CDF. Book in PDF, ePub and Kindle
We present a precision measurement of the top-quark mass using the full sample of Tevatron √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 signal and background samples to extract the top-quark mass and the energy scale of the calorimeter jets with in situ calibration. The likelihood fit of the templates from signal and background events to the data yields the single most-precise measurement of the top-quark mass, mtop = 172.85 ± 0.71 (stat) ± 0.85 (syst) GeV/c2.
