Available in PDF, EPUB and Kindle. Book excerpt: The authors present a measurement of the $ar{p}$p → W? + X → ev? + X production cross section using data form the Collider Detector at Fermilab. The p$ar{p}$ collisions were provided by the Tevatron Collider at a center of mass energy of 1.96 TeV. Electroweak theory includes the trilinear vector boson coupling, WW?, which contributes to the ev? final state. The electron decay channel of the W provides a clean sample to study the production of diboson pairs. The measurement of the production cross section tests the structure of the non-Abelian character of Electroweak theory.

This book was released on 2004 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-precision measurements are made of Z boson production in proton-antiproton collisions at √s = 1.96 TeV recorded by the Collider Detector at Fermilab, using the electron decay channel. The cross-section times branching ratio is measured to be ?Z · Br(Z → e+e-) = (255.7 ± 2.4stat ± 5.2sys ± 15.2lum)pb in a dataset of 194 pb-1 collected between March 2002 and June 2003. This agrees well with theoretical predictions. The cross-section for W boson production in the electron channel has also been measured in the subset of this dataset of 72 pb-1 collected up until January 2003. Using this smaller dataset the ratio of cross-sections is determined to be R ≡ ?W · Br(W → e?)/?Z · Br(Z → ee) = 10.82 ± 0.18stat ± 0.16sys. Combining these results with measurements made in the muon channel gives R = 10.92 ± 0.15stat ± 0.14sys (e + ? channels), from which the branching ratio of the W to electrons and muons, and the total width of the W, have been extracted: Br(W → l?) = 0.1089 ± 0.0022 (l = e,?); ?(W) = 2078.8 ± 41.4 MeV, which are in good agreement with the Standard Model values and with other measurements.

Available in PDF, EPUB and Kindle. Book excerpt: The Collider Detector at Fermilab (CDF) was used to measure the transverse momentum distribution of W boson produced in proton-antiproton collisions at the Tevatron collider. The W bosons were identified by the decay W 2!e[nu]. The results are in good agreement with a next-to-leading order calculation. The cross section for W production with P{sub T}> 50 GeV/c is 423 {plus minus} 58 (stat.) {plus minus} 108 (sys.) pb. 58 refs., 53 figs., 16 tabs.

This book was released on 2004 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: A preliminary measurement of the t$ar{t}$ production cross section at √s = 1.96 TeV is presented. The ?-plus-jets final state is analyzed in a data sample of 94 pb-1 and a total of 14 events are selected with a background expectation of 11.7 ± 1.9 events. The measurement yields: ?p$ar{p}$ → t$ar{t}$ + X} = 2.4$+4.2top{-3.5}$(stat.)$+2.5top{-2.6}$(syst.) ± 0.3(lumi.) pb. The analysis, being part of a larger effort to re-observe the top quark in Tevatron Run II data and to measure the production cross section, is combined with results from all available analyses channels. The combined result yields: ? p$ar{p}$ → t$ar{t}$ + X = 8.1$+2.2top{-2.0}$(stat.)$+1.6top{-1.4}$(syst.) ± 0.8(lumi.) pb.
