Book Description
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 Description
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.

Book Description
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 Description
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. In this article, recent top quark physics results from CDF and D0 are reported. In particular, measurements of single top quark and double top quark production, the $t\bar{t}$ forward-backward asymmetry and the top quark mass are discussed.

Book Description
This book discusses recent developments in both the theoretical and the experimental aspects of QCD. Its main goal is to establish precise predictions of the Standard Model in order to find clues to the discovery of New Physics.

Book Description
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.
