Top Mass from Electroweak Measurements
Bob Jacobsen
TL;DR
This paper reports on electroweak measurements from LEP data (1989-1993) that support the Standard Model and provide a combined fit estimating the top quark and Higgs boson masses.
Contribution
It presents a preliminary analysis of electroweak data that constrains the top quark and Higgs boson masses within the Standard Model framework.
Findings
Estimated top quark mass: 177 +11 -11 +18 -19 GeV/c2
Good agreement with Standard Model predictions
Combined fit constrains Higgs boson mass
Abstract
The electroweak measurements made at LEP using 1989-1993 data are presented in preliminary form. The agreement with the Standard Model is satisfactory, and allows a combined fit to all available data for the masses of the top quark and standard Higgs boson. The fit yields M_t = 177 +11 -11 +18 -19 GeV/c2, where the second error reflects the uncertainty in the Higgs mass.
