We propose a model that explains the fermion mass hierarchy by the Froggatt-Nielsen mechanism with a discrete Z_N flavor symmetry. As a concrete model, we study a supersymmetric model with a single ﬂavon coupled to the minimal supersymmetric Standard Model. Flavon develops a TeV scale vacuum expectation value for realizing ﬂavor hierarchy, an appropriate µ-term and the electroweak scale, hence the model has a low cutoﬀ scale. We demonstrate how the ﬂavon is successfully stabilized together with the Higgs bosons in the model. The discrete ﬂavor symmetry Z_N controls not only the Standard Model fermion masses, but also the Higgs potential and a mass of the Higgsino which is a good candidate for dark matter. The hierarchy in the Higgs-ﬂavon sector is determined in order to make the model anomaly-free and realize a stable electroweak vacuum. We show that this model can explain the fermion mass hierarchy, realistic Higgs-ﬂavon potential and thermally produced dark matter at the same time. We discuss ﬂavor violating processes induced by the light ﬂavon which would be detected in future experiments.
