Top mass and cross section results from CDF and D0 at the Fermilab Tevatron

PDF Version Also Available for Download.

Description

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 {approx}100 pb{sup -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 {plus_minus} 4:0(stat) {plus_minus} 5:1(syst) GeV/c{sup 2} and M{sub t} = 172:1 {plus_minus} 5:2(stat) {plus_minus} 4:9(syst) GeV/c{sup 2} , respectively. The combined Tevatron top quark mass is M{sub t} = 174:3 ... continued below

Description

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 {approx}100 pb{sup -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 {plus_minus} 4:0(stat) {plus_minus} 5:1(syst) GeV/c{sup 2} and M{sub t} = 172:1 {plus_minus} 5:2(stat) {plus_minus} 4:9(syst) GeV/c{sup 2} , respectively. The combined Tevatron top quark mass is M{sub t} = 174:3 {plus_minus}3:2(stat) {plus_minus}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 {plus_minus} 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.
