“…This pattern of Higgs soft masses are consistent with the condition for the stable EW minimum discussed in the previous subsection. This feature was pointed out in the Z 3 invariant NMSSM [104]. The NUGM scenario is realized in GUT models [105][106][107][108][109][110][111][112] as well as the so-called mirage mediation [113][114][115][116][117][118].…”

We propose a model that explains the fermion mass hierarchy by the Froggatt-Nielsen mechanism with a discrete Z F N 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 F 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. N sym-1 Recently, it is proposed that a flavon can be identified as the QCD axion [3-8] 2 See, e.g., Refs. [35,36] for recent models with a flavor modular symmetry and also for such interactions in string models.3 Models with a combination of Higgs doublets H u H d as a flavon are studied in Refs. [41][42][43].

Supermassive gauginos in supergravity inflation with high-scale SUSY breaking

A model of supergravity inflation we recently proposed can produce slow roll inflation and a realistic spectrum of particles even without F-term supersymmetry breaking. Supersymmetry is broken only by a D-term induced by a recently discovered new type of Fayet-Iliopoulos (FI) term. Almost all supersymmetric partners of the standard model fields can get masses as high as the inflationary Hubble scale. The exception is gauginos, for which the vanishing of F-terms implies an exact cancellation that keeps their masses exactly zero. To cure this problem without spoiling the simplicity of our model we introduce a new term that further enlarges the space of supergravity effective actions. It is an F-term that, similarly to the new FI term, becomes singular in the supersymmetric limit. We show that this term can produce large gaugino masses without altering the spectrum of other states and without lowering the cutoff of the effecive theory.
