Imminent Phenomenology of a Minimal Gauge-Mediated Model

Abstract

We calculate the inclusive branching ratio for B--> X_s gamma, the inclusive branching ratios and asymmetries for B--> X_s l+ l- and the anomalous magnetic moment g-2 of the muon, within a minimal gauge-mediated SUSY-breaking model which naturally generates a large ratio tan(beta) 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 B--> X_s gamma decay and g-2 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 B--> X_s e+ e- and B--> X_s mu+ mu- asymmetries, and somewhat smaller ones in B--> X_s e+ e- and B--> X_s tau+ tau- branching ratios, which will be detectable in hadronic colliders.
