Abstract

We revisit phenomenology of the minimal gauge-mediated model. This model is motivated from the SUSY CP and flavor problems. A specific feature of this model is that tan β is naturally large, since the B term in the Higgs potential is zero at the messenger scale. This leads to significant SUSY contributions to various low-energy observables. We evaluate the anomalous magnetic moment of the muon and the branching ratio of over(B, ̄) → Xs γ taking account of recent theoretical and experimental developments. We find that the current experimental data prefer a low messenger scale (∼ 100 TeV) and gluino mass around 1 TeV. We also calculate the branching ratios of over(B, ̄) → Xs l+ l-, Bs → μ+ μ-, and B- → τ- over(ν, ̄), and show that these observables are strongly correlated with each other in this model.
