Low-Energy Signals for a Minimal Gauge-Mediated Model

The inclusive branching ratio $B \to X_s\gamma$ and the anomalous magnetic moment $g_\mu-2$ of the muon are accurately calculated within a minimal gauge-mediated SUSY-breaking model which naturally generates a large $\tan\beta$. The predictions are in somewhat better agreement with current experiments, and new data will soon critically test these predictions. Predictions for $B \to X_s\ell^+\ell^-$ branching ratios and asymmetries, to be tested at future colliders, are also presented.
