Precision tests of the Electroweak interactions at e+e- collisions
F. Teubert (CERN)
TL;DR
This paper reviews high-precision electroweak measurements from LEP and SLC, confirming the Standard Model's predictions and providing indirect estimates for the top quark, W boson, and Higgs boson masses.
Contribution
It presents an updated analysis of electroweak precision tests, demonstrating sensitivity to weak radiative corrections and constraining fundamental particle masses.
Findings
Top quark mass estimated at 180 ± 10 GeV
W boson mass measured at 80.375 ± 0.022 GeV
Higgs boson mass upper limit set at 196 GeV
Abstract
This paper is an updated version of the lectures given at the XXIX International Meeting on Fundamental Physics in Sitges, Barcelona (February 2000). The measurements perforned at LEP and SLC have substantially improved the precision of the test of the Minimal Standard Model. The precision is such that there is sensitivity to pure weak radiative corrections. This allows to indirectly determine the top mass (m_t = 180 +- 10GeV), the W-boson mass (M_W = 80.375 +- 0.022GeV), and to set an upper limit on the Higgs boson mass of 196GeV at 95% confidence level.
