New mechanism of generating flavor mass spectrum is proposed by using an O'Raifeartaigh-type supersymmetry breaking model. A desired bilinear form of fermion mass spectrum is naturally realized through F-components of gauge-singlet (nonet of SU(3) flavor symmetry) superfields, and the suitable charged-lepton mass relation is reproduced. The charged-slepton mass spectrum is non-degenerate in general, and can be even hierarchical (proportional to the charged-lepton masses in the specific case…

Family gauge symmetry as an origin of Koide's mass formula and charged lepton spectrum
Koide's mass formula is an empirical relation among the charged lepton masses which holds with a striking precision. We present a model of charged lepton sector within an effective field theory with
A modified version of the Koide formula from flavor nonets in a scalar potential model and in a Yukawaon model
We present a modified version of the Koide formula from a scalar potential model or from a Yukawaon model, based on scalar fields set up in a nonet representation of the SU(3) flavor symmetry in the
How to Evade a No-Go Theorem in Flavor Symmetries
A no‐go theorem in flavor symmetries is reviewed. The theorem asserts that we cannot bring any flavor symmetry into mass matrix model in which number of Higgs scalars is, at most, one for each sector


New Origin of a Bilinear Mass Matrix Form
A charged lepton mass formula is explained when the masses are proportional to the squared vacuum expectation values (VEVs) of scalar fields. We introduce a U(3) flavor symmetry and its nonet scalar
Small Neutrino Masses from Supersymmetry Breaking
An alternative to the conventional see-saw mechanism is proposed to explain the origin of small neutrino masses in supersymmetric theories. The masses and couplings of the right-handed neutrino field
S4 flavor symmetry embedded into SU(3) and lepton masses and mixing
Based on the assumption that an S4 flavor symmetry is embedded into SU(3), a lepton mass matrix model is investigated. A Froggatt-Nielsen type model is assumed, and the flavor structures of the
Lepton family symmetry and possible application to the Koide mass formula
Abstract A finite group generated by four Z 3 transformations is applied to lepton families in a supersymmetric model, resulting in the charged-lepton masses m i being proportional to v i 2 , where v
Hierarchy of Quark Masses, Cabibbo Angles and CP Violation
Some ideas are put forward towards understanding the fact that mass ratios of quarks or leptons are usually rather large. These speculations are based on the assumption that the basic (bare)
Charged lepton mass sum rule from U(3)-family Higgs potential model
In this paper, the authors assume U(3)-family nonet Higgs scalars which couple to charge leptons bilinearly, a simple Higgs potential with a term which breaks the U(3)-family into SU(3)-family will
A fermion-boson composite model of quarks and leptons
Abstract Quark and lepton masses and flavor-mixing angles are estimated on the basis of a fermion-boson composite model where the (u, d), (c, s) and (t, b) quarks are assigned to the diagonal
New view of quark and lepton mass hierarchy
The hierarchical structure of realistic quark and lepton masses is investigated on the basis of a three-family model, where masses and mixings of the first- and second-generation quarks are

This paper describes an approach to model building with supersymmetry broken at comparatively low energies which solves these problems, and gives a realistic example.
Spontaneous symmetry breaking for chirals scalar superfields
Abstract The spontaneous breakdown of supersymmetry and internal symmetry is studied for the interaction of N chiral scalar superfields. A lemma is established which shows that the spontaneous
