After the issuing of new top mass results by the Tevatron experiments, it is time for another look at global electroweak fits of standard model observables. The Gfitter group
has produced new fits for the standard model in search of the most probable value of the Higgs boson mass, given the new measurements of top quark mass and other quantities, and the huge amount of existing information on sensitive observables from the standard model.
Unfortunately, I could find no update including the new Higgs search results yet. I guess such a fit will be ready in a few weeks... But the new released information is already interesting enough that we may meaningfully spend a few words around some figures here.
