Book excerpt: This dissertation describes a direct measurement of the W boson total decay width, [Lambda][sub W], using the D0 detector at the Fermilab Tevatron Collider. The measurement uses an integrated luminosity of 177.3 pb[sup -1] data, collected during the 2002-2003 run. The width is determined from the shape of the transverse mass distribution, M[sub T], by fitting the data in the tail region 100

Book excerpt: A direct measurement of the W boson total decay width is presented in proton-antiproton collisions at (square root)s = 1.96 TeV using data collected by the CDF II detector. The measurement is made by fitting a simulated signal to the tail of the transverse mass distribution in the electron and muon decay channels. An integrated luminosity of 350 pb−1 is used, collected between February 2002 and August 2004. Combining the results from the separate decay channels gives the decay width as 2.038 ± 0.072 GeV in agreement with the theoretical prediction of 2.093 ± 0.002 GeV. A system is presented for the management of detector calibrations using a relational database schema. A description of the implementation and monitoring of a procedure to provide general users with a simple interface to the complete set of calibrations is also given.

This book was released on 1994 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present results from W and Z boson production in proton-antiproton collisions at √s = 1.8 TeV using the CDF detector. We measure the W and Z cross sections times lepton branching ratio, [sigma](p{bar p} → W)·B(W → l[nu]{sub l}) and [sigma](p {bar p} → Z)· B(Z → k+l−) l = e, [mu]. We also measure the ratio: R{sub l} = [sigma] · B(W → l[nu]{sub l})/[sigma] · B(Z → ll). From R{sub l}, we extract the W electron and muon branching ratios, BR(W → l[nu]{sub l}, and the total W width, [Gamma]{sub W}. In addition, high transverse mass W →e[nu]{sub e}, candidates provide an alternate, direct measurement of [Gamma]{sub W}.

Luchini and published by . This book was released on 1994 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We have measured the production cross sections x decay branching ratios for W + $gamma$ and Z + $gamma$ in the muon channel in $sqrt{s}$ = 1.8 TeV p-p collisions, from 3.54 $pm$ 0.24 $pbsp{-1}$ of muon W and Z data from the CDF 1988-89 Tevatron collider run. For photons in the central region ($vertetavert $ 5.0 GeV and lepton-photon angular separation $Delta Rsb{ellsbgamma} >$ 0.7, 5 $Wsb{gamma}$ candidates and 2 $Zsb{gamma}$ candidates were observed. From these events, the $sigma cdot BR(W + gamma)$ and $sigma cdot BR(Z + gamma)$ cross sections for the muon samples are measured, and compared with Standard Model predictions. We also determined the cross section ratios, $Wsb{gamma}$/W, $Zsb{gamma}$/Z and $Wsb{gamma}/Zsb{gamma}$, which, along with the previous CDF measurement(s) of the W/Z cross section ratio provide new insight on the Standard Model, and are sensitive to anomalous couplings of the W and Z bosons. Using the $Wsb{gamma}$ and $Zsb{gamma}$ absolute cross section measurements, the absence of an excess of hard photons accompanying W and Z boson production enables us to obtain direct limites on anomalous $WWsb{gamma}$, $ZZsb{gamma}$ and $Zsb{gammagamma}$ couplings. For saturation of unitarity, these experimental limits impose constraints on possible internal (composite) structure for the W and Z bosons with compositeness scale sensitivity up to $Lambdasb{W} sim$ 1 TeV and $Lambdasb{Z} sim$ 250-500 GeV, respectively. These compositeness scale limits probe the possible internal structure of the W to ${sim}
