Imminent phenomenology of a minimal gaugemediated model
Abstract
We calculate the inclusive branching ratio for B>X_{s}γ, the inclusive branching ratios and asymmetries for B>X_{s}l^{+}l^{}, and the anomalous magnetic moment g_{μ}2 of the muon, within a minimal gaugemediated supersymmetrybreaking 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 B>X_{s}γ 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 B>X_{s}e^{+}e^{} and B>X_{s}μ^{+}μ^{} asymmetries, and somewhat smaller ones in B>X_{s}e^{+}e^{} and B>X_{s}τ^{+}τ^{} branching ratios, which will be detectable in hadronic colliders.
