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 H"00 pb−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 ± 4:0(stat) ± 5:1(syst) GeV/c{sup 2} and M{sub t} = 172:1 ± 5:2(stat) ± 4:9(syst) GeV/c{sup 2}, respectively. The combined Tevatron top quark mass is M{sub t} = 174:3 ±3:2(stat) ±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 ± 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: The authors present the latest results about top physics obtained by the CDF experiment at the Fermilab Tevatron collider. The data sample used for these analysis (about 110 pb−1) represents almost the entire statistics collected by CDF during four years (1992--95) of data taking. This large data size has allowed detailed studies of top production and decay properties. The results discussed here include the determination of the top quark mass, the measurement of the production cross section, the study of the kinematics of the top events and a look at top decays.

Furthermore, I will review the measurements of the forward-backward asymmetry in tt-bar events, and conclude with the world's most precise single measurement of the top quark mass, which is a fundamental parameter of the standard model, and present the Tevatron combination, which is the world's most precise determination of the top quark mass, with a relative precision of 0.37%.
