Abstract: (arXiv)
A model independent analysis of the most recent averages of precision electroweak data from LEP and SLD finds a 3 deviation of the parameter from the Standard Model prediction. The fitted value of shows a strong dependence on the inclusion or exclusion of b quark data, and the Standard Model fits have poor confidence levels of a few percent when the latter are included. The good fits obtained to lepton data, c quark data and the directly measured top quark mass, give GeV and indicate that the Higgs boson mass is most likely less than 200 GeV.Note:
