MSSM and Z width: implications on top quark and Higgs physics
Abstract
We discuss the one-loop quantum corrections to the top quark width and to the hadronic widths of the Higgs bosons of the MSSM, and emphasize the results obtained in particular regions of the MSSM parameter space which have been proposed to alleviate the anomalies observed in the decay modes of the Z into bb and cc. We find that the corrections can be large and should be visible through the measurement of the top quark production cross-sections in future experiments at the Tevatron and at the LHC.
