Status of the global fit to electroweak precisions data

In this presentation Gfitter results from the global Standar d 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 αS(M 2) = 0.1193± 0.0028(exp)± 0.0001(theo). In addition the electroweak fit has been performed with the top mass determin ed from the pp ! tt + X crosssection as measured at Tevatron.
