Status of the global fit to electroweak precisions data
Abstract
In this presentation Gfitter results from the global Standard Model (SM) fit to electroweak precision data are discussed. We have used the latest measurements of mtop and MW and the most recent results for direct Higgs searches at LEP and Tevatron. We obtain MH=121+17-6 GeV and a 95% CL upper limit of 155 GeV for the SM Higgs mass. The forth-order result for the strong coupling constant is given by alphaS(MZ2)=0.1193 +- 0.0028(exp) +- 0.0001(theo). In addition the electroweak fit has been performed with the top mass determined from the ttbar cross-section as measured at Tevatron.
