The top quark and Higgs boson masses in the standard model and the MSSM
Abstract
We update the precision electroweak prediction of mt, making a global analysis including low-energy data as well as the latest LEP and SLC data, and compare it with the mass indicated by CDF measurements: theory and experiments match within errors. In view of the excellent agreement, we combine the information on mt to sharpen indications on MH, finding a central value around 100 GeV, in agreement with the prediction of the Minimal Supersymmetric extension of the Standard Model (MSSM). Our most complete fit gives mt= 162±9GeV, with MH free. We also present bounds from precision electroweak data on the sfermion and gaugino masses in the MSSM, which are competitive with direct limits from CDF, and exclude charginos close to the present mass limits.
