Article Description

We calculate the inclusive branching ratio for (Formula presented) the inclusive branching ratios and asymmetries for (Formula presented) and the anomalous magnetic moment (Formula presented) of the muon, within a minimal gauge-mediated supersymmetry-breaking model which naturally generates a large ratio (Formula presented) of Higgs field vacuum expectation values. These predictions are highly correlated with each other, depending on only two fundamental parameters: the superpartner mass scale and the logarithm of a common messenger mass. The predictions for (Formula presented) decay and (Formula presented) are in somewhat better agreement with current experiments than the standard model, but a much sharper comparison will soon be possible using new measurements now in progress or under analysis. Moreover we predict large deviations in (Formula presented) and (Formula presented) asymmetries, and somewhat smaller ones in (Formula presented) and (Formula presented) branching ratios, which will be detectable in hadronic colliders. © 1998 The American Physical Society.
