Available in PDF, EPUB and Kindle. Book excerpt: CDF and D0 have published or submitted for publication eleven papers [1-11] that include direct experimental measurements of the top quark mass. Each experiment has found that the lepton+jets channel [1,5,6,9,10,11,12] gives the most precise result. However, CDF and D0 have also measured the top quark mass in other decay topologies. Both D0 [2,6] and CDF [3,4] have published additional results in the dilepton channels, while CDF [8] has published a result in the all-hadronic channel. Our aim in this note is to reduce the overall uncertainty on the top quark mass measurement by combining the most recent and final of these measurements [1,2,3,7,8]. This note combines the mass from the five separate measurements taking into account the statistical and systematic uncertainties as well as the correlations in the systematic uncertainties. The final Tevatron top mass based on Run 1 data is m{sub t} = 174.3 " 3.2(stat) " 4.0(syst) GeV/c2. Combining the statistical and systematic uncertainties, the top mass is m{sub t} = 174.3 " 5.1 GeV/c2.
Book Synopsis Combination of CDF and D0 Results on the Mass of the Top Quark by : T. Maruyama
Download or read book Combination of CDF and D0 Results on the Mass of the Top Quark written by T. Maruyama and published by . This book was released on 2006 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: We summarize the top-quark mass measurements from the CDF and D0 experiments at Fermilab. We combine published Run-I (1992-1996) measurements with the most recent preliminary Run-II (2001-present) measurements using up to 750 pb{sup -1} of data. Taking correlated uncertainties properly into account the resulting preliminary world average mass of the top quark is M{sub t} = 172.5 {+-} 1.3(stat) {+-} 1.9(syst) GeV/c{sup 2}, which corresponds to a total uncertainty of 2.3 GeV/c{sup 2}. The top-quark mass is now known with a precision of 1.3%--a 20% improvement relative to the previous combination.

Available in PDF, EPUB and Kindle. Book excerpt: We summarize the top-quark mass measurements from the CDF and D0 experiments at Fermilab.

Taking correlated uncertainties properly into account the resulting preliminary world average mass of the top quark is M{sub t} = 171.4 ± 1.2(stat) ± 1.8(syst) GeV/c2, which corresponds to a total uncertainty of 2.1 GeV/c2. The top-quark mass is now known with a precision of 1.2%.

Download or read book Combination of CDF and D0 Results on the Mass of the Top Quark Using Up to 5.8~fb-1 of Data written by and published by . This book was released on 2011 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: We summarize the top-quark mass measurements from the CDF and D0 experiments at Fermilab. We combine published Run I (1992--1996) measurements with the most precise published and preliminary Run II (2001--present) measurements using up to 5.8 fb−1 of data, adding new analyses (the missing transverse energy plus jets analysis) and updating old ones. Taking uncertainty correlations into account, and adding in quadrature the statistical and systematic uncertainties, the resulting preliminary Tevatron average mass of the top quark is M{sub t} = 173.2 ± 0.9 GeV/c2.
Book Synopsis The Evidence for the Top Quark by : Kent W. Staley
Download or read book The Evidence for the Top Quark written by Kent W. Staley and published by Cambridge University Press. This book was released on 2004-04-05 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Evidence for the Top Quark offers both a historical and philosophical perspective on an important recent discovery in particle physics: the first evidence for the elementary particle known as the top quark. Drawing on published reports, oral histories, and internal documents from the large collaboration that performed the experiment, Kent Staley explores in detail the controversies and politics that surrounded this major scientific result.At the same time the book seeks to defend an objective theory of scientific evidence based on error probabilities.

Download or read book Top Mass and Cross Section Results from CDF and D0 at the Fermilab Tevatron written by and published by . This book was released on 2000 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Measurements of the top quark mass and the t[bar t] production cross section, obtained by CDF and D0 Collaborations at the Tevatron, are presented. The methodology of analyses and their underlying assumptions are summarized. The CDF and D0 top mass averages, based on [approx]100 pb[sup -1] of data collected by each experiment in Run-I, and obtained from a set of selected measurements in several channels are M[sub t] = 176:0 [plus-minus] 4:0(stat) [plus-minus] 5:1(syst) GeV/c[sup 2] and M[sub t] = 172:1 [plus-minus] 5:2(stat) [plus-minus] 4:9(syst) GeV/c[sup 2], respectively. The combined Tevatron top quark mass is M[sub t] = 174:3 [plus-minus]3:2(stat) [plus-minus]4:0(syst) GeV/c]sup 2], where the correlations between CDF and D0 averages were taken into account. The CDF measurement of the t[bar t] cross section (assuming M[sub t] = 175 GeV/c[sup 2]) is [sigma][sub tt] = 7.6[sup 1.8][sub 1.5] pb, and the D0 value (assuming M[sub t] = 172.1 GeV/c[sup 2]) is [sigma][sub tt] = 5:9 [plus-minus] 1:7 pb. In anticipation of the much increased statistics in Run-II, the fact that top quark physics is one of the best windows to new physics beyond the Standard Model is emphasized.

Book excerpt: A summary of the most up-to-date top quark mass measurements at CDF is presented. These analyses use top-antitop candidate events detected in the CDF experiment at the Tevatron collider with an integrated luminosity of up to (almost equal to)3/fb. The combination of all those measurements together with the corresponding top mass measurements from the concurrently running D0 experiment at the Tevatron yields a world average of M{sub t} = [173.1 ± 0.6(stat.) ± 1.1(syst.)] GeV/c2.
