In a model where quark and lepton masses and family-mixings are caused not by a variety of Yukawa couplingsyij(i,j=1, 2, 3: family indices) with one vacuum expectation value (VEV)ν=〈φL0〉0, but by a variety of VEV’s of a U(3)-family nonet Higgs bosonφL,vij=〈φLi0j〉0, with a single coupling constant, the following problems are investigated: what constraints on the Higgs potential are imposed in order to provide realistic quark and lepton mass spectra and mixings and what constraints on the Higgs…

Flavor structure from flavored Higgs mixing
In this paper, we suggest a simple model which induces realistic flavor structure from mixing of flavored Higgs doublets. The idea is based on the decoupling limit. In a model with many Higgs
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
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
Seesaw mass matrix model of quarks and leptons with flavor-triplet Higgs scalars
In a seesaw mass matrix model $M_f = m_L M_F^{-1} m_R^\dagger$ with a universal structure of $m_L \propto{m}_R$, as the origin of mL (mR) for quarks and leptons, flavor-triplet Higgs scalars whose
S3 symmetry and neutrino masses and mixings
Based on the universal seesaw mass matrix model with the three scalars φi, and by assuming S3 flavor symmetry for the Yukawa interactions, the lepton masses and mixings are investigated
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
A4 symmetry and lepton masses and mixing
AbstractStimulated by Ma’s idea, which explains the tribimaximal neutrino mixing by assuming an A4 flavor symmetry, a lepton mass matrix model is investigated. A Frogatt–Nielsen-type model is
A New Empirical Approach to Quark and Lepton Masses
We present an alternative to the Koide formula and it’s extensions. By introducing two parameters k and ↵f derived from charged leptons we are able to construct new empirical formulas that appear to
Tribimaximal neutrino mixing and a relation between neutrino- and charged lepton-mass spectra
In a universal seesaw model Mf = mfLM−1FmfR, we require the following constraints: (i) the heavy-lepton mass matrices ME and MN are proportional to a unit matrix. (ii) meL is diagonal and the mass
An empirical neutrino mass matrix related to up-quark masses
Based on an approach to quark and lepton masses, where the mass spectra originate in vacuum expectation values of U(3) flavor nonet (gauge singlet) scalars, neutrino masses and mixing are

SEE-SAW MASSES FOR QUARKS AND LEPTONS IN AN AMBIDEXTROUS ELECTROWEAK INTERACTION MODEL
An ambidextrous electroweak interaction model with SU(2)L×SU(2)R×U(1) gauge symmetry is described in which the conventional quarks and leptons are accompanied by a set of new fermions that transform
Universal Seesaw Mechanism for Quarks and Leptons
2GeV scale of the yet-undiscovered top quark is explained without presuming unnaturally huge mass scales. A global horizontal U(I)A symmetry is introduced so as to circumvent the strong CP violation

Problems of fermion mass hierarchies and generation mixings are investigated through universal seesaw mechanisms (USM's) in an extension of the standard model with a left-right-symmetric gauge group
Quark mass hierarchies from the universal seesaw mechanism.
TLDR
A systematic perturbative technique is developed and it is proved that there exists an open subdomain in the parameter space where the orbit of the lowest minima of the potential corresponds to the kind of hierarchy in the vacuum expectation values needed for the success of the model.
Quark masses and cabibbo angles
Abstract A simple symmetric pattern of Higgs fields in an SU (2) L × SU (2) R × U (1) gauge model with six quarks yields: tan 2 θ c = m d / m s and θ c = 15° in good agreement with experiment. A

TLDR
The singlet fermion masses lie in the 100-GeV to 1-TeV range to be probed by the oncoming accelerators of the 1990s and the definition of the Fermi coupling constant and neutrino neutral-current interactions are identical to those of the standard SU(2)/sub L/ x U(1) 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
Horizontal gauge symmetry and a new picture for the b quark
We attempt to use a horizontal gauge symmetry in addition to SU(2)/sub L/ x U(1) to understand Cabibbo universality and the fermion masses. We compute the mixing angle between the light (u,d,s,c) and
Universal Seesaw and Radiative Quark Mass Hierarchy
A new approach to the fermion mass problem is suggested. The mass hierarchy is first radiatively generated in a sector of heavy isosinglet fermions and then projected to the visible ones by means of

TLDR
A particular scheme which allows the determination of the Kobayashi-Maskawa matrix elements in terms of the quark masses is discussed, and constraints on the strange- and the top-quark masses are obtained.
