Available in PDF, EPUB and Kindle. Book excerpt: We present the recent results on top quark physics and B physics with the Collider Detector at Fermilab (CDF). These results come from analyses using a full data sample at an integrated luminosity of 109 pb−1 cross section in 1.8-TeV p{anti p} collisions. We measure the top quark mass to be 175.8±6.5 GeV/c2 and the t{anti t} production cross section to be 7.6{sup +1.8}{sub -1.5} pb. We also present measurements of the lifetimes of B-hadrons and the time- dependent B°-{anti B}° mixing which results in the mass difference between heavy and light B°{sub d} mesons ([Delta]m{sub d}) of 0.464±0.030(stat)±0.026(syst) ps−1.

Book excerpt: We present the latest results on the top quark obtained by the CDF experiment using a data sample of about 110 pb[sup -1]. The data sample has been collected at the FermiLab Tevatron Collider with p[anti p] collisions at[radical]s= 1.8 TeV. We briefly describe the candidate event selection and then discuss the production cross section determination and the mass measurement. Combining the results from the channels with at least one W decaying leptonically into an electron or muon, we measure[sigma][sub t[anti t]]= 7.5[sup+1.9][sub -1.6] pb. Our best measured value for the top mass gives M[sub t]= 176.8[+-]6.5 GeV/c[sup 2]. We also report on the observation of t[anti t] production in the all hadronic decay channel using kinematic selection and b identification, and in the channel containing one hadronically decaying[tau] lepton. Finally we discuss the kinematics of top events and measure the matrix element[vert-bar]V[sub tb][vert-bar]=1.12[+-]0.12.

Available in PDF, EPUB and Kindle. Book excerpt: This will be a required acquisition text for academic libraries. More than ten years after its discovery, still relatively little is known about the top quark, the heaviest known elementary particle. This extensive survey summarizes and reviews top-quark physics based on the precision measurements at the Fermilab Tevatron Collider, as well as examining in detail the sensitivity of these experiments to new physics. Finally, the author provides an overview of top quark physics at the Large Hadron Collider.

Book excerpt: Twenty years after its discovery in 1995 by the CDF and D0 collaborations at the Tevatron proton-antiproton collider at Fermilab, the top quark still undergoes intensive studies at the Tevatron and the LHC at CERN.

Book excerpt: The existence of the top quark, discovered by CDF and D0 in 1995, has been re-established in the burgeoning dataset being collected in Run 2 of the Tevatron at Fermilab. Results from CDF on the top quark production cross section and top quark mass are consistent with the Standard Model expectations. The well-characterized top data samples will make it possible in the future to probe further for new physics in the top quark sector. This report summarizes recent CDF top quark physics results.

Book excerpt: We present recent results from the Collider Detector at Fermilab. Searches for the top quark have established a lower bound of M{sub top}> 91 GeV/c2 (at 95% confidence level). A measurement of B{sup o}{bar B}{sup o} mixing has been obtained from b{bar b} 2!e[mu], ee events. Measurements of b-quark production have been obtained from e + X events and J/[psi] + K events. The mass of the W boson has been determined to be M{sub W} = 79.91 {plus minus} 0.39 GeV/c2. In searching for new gauge bosons, we have obtained the bounds M{sub Z{prime}}> 412 GeV/c2 and M{sub W{prime}}> 520 GeV/c2 (at 95% C.L.). The lower limits on the quark and lepton compositeness scales are 1.4 TeV. In the next two years of data collection, we expect significantly more events for numerous types of physics, due to 25 times more beam luminosity, and improvement to the detector. In the longer term, the Main Injector'' upgrade to the accelerator, further improvements to the detector are being planned to exploit the potentials for physics. We discuss prospects for the discovery of the top quark, precise measurement of properties of b quark, and searches for new physics beyond the Standard Model. 29 refs.

Book excerpt: Fermilab's Tevatron accelerator is recently performing at record luminosities that enables a program systematically addressing the physics of top quarks. The CDF collaboration has analyzed up to 5 fb−1 of proton anti-proton collisions from the Tevatron at a center of mass energy of 1.96 TeV. The large datasets available allow to push top quark measurements to higher and higher precision and have lead to the recent observation of electroweak single top quark production at the Tevatron. This article reviews recent results on top quark physics from the CDF experiment.

Available in PDF, EPUB and Kindle. Book excerpt: Twelve years after the discovery of the top quark at Fermilab's Tevatron, they are now finally beginning to shed light on this peculiarily massive quark. With 1-1.7 fb−1 of integrated luminosity collected by the CDF detector, they are able to probe the knowledge of the top quark physics, and to search for signals of physics beyond the Standard Model. In this paper, they present results of measurements of top quark properties, as well as tests for the production mechanism of the top quark. They also describe CDF latest searches for beyond Standard Model couplings of the top quark. Finally, they present the most recent searches for direct production of new particles in the collected data samples.

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.
