Imminent phenomenology of a minimal gauge-mediated model

We calculate the inclusive branching ratio for →BXₛγ, the inclusive branching ratios and asymmetries for →BXₛl⁺l^-, and the anomalous magnetic moment g_μ-2 of the muon, within a minimal gauge-mediated supersymmetry-breaking model which naturally generates a large ratio tanβ 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 →BXₛγ decay and g_μ-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 →BXₛe⁺e^- and →BXₛμ⁺μ^- asymmetries, and somewhat smaller ones in →BXₛe⁺e^- and →BXₛτ⁺τ^- branching ratios, which will be detectable in hadronic colliders.
