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 assumed, and the flavor structures of the masses and mixing are caused by the VEVs of SU(2)L singlet scalars φiu and φid (i=1,2,3), which are assigned to 3 and (1 ,1 ’,1 ”) of A4, respectively. Possible charged lepton and neutrino mass spectra and mixing are investigated. 
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
A New S 4 Flavor Symmetry in 3-3-1 Model with Neutral Fermions
A new S 4 flavor model based on SU(3) C ⊗ SU(3) L ⊗ U(1) X gauge symmetry responsible for fermion masses and mixings is constructed.Theneutrinos get smallmasses fromonly an antisextet of SU(3)L which
Lepton masses in a minimal model with triplet Higgs bosons and S 3 flavor symmetry
Viable neutrino and charged lepton masses and mixings are obtained by imposing a S{sub 3}xZ{sub 4}xZ{sub 3} flavor symmetry in a model with a few additional Higgs. We use two SU(2){sub L} triplet
A4flavor symmetry and neutrino phenomenology
It has been shown that tribimaximal mixing can be obtained by some particular breaking pattern of the A{sub 4} symmetry, wherein the extra A{sub 4} triplet Higgs scalars pick up certain fixed vacuum
The interplay between GUT and flavour symmetries in a Pati-Salam × S4 model
Both Grand Unified symmetries and discrete flavour symmetries are appealing ways to describe apparent structures in the gauge and flavour sectors of the Standard Model. Both symmetries put
Non-Abelian discrete flavor symmetries
This is an incomplete survey of some non-Abelian discrete symmetries which have been used recently in attempts to understand the flavor structure of leptons and quarks. To support such symmetries,
Embedding A(4) into SU(3) x U(1) flavor symmetry: large neutrino mixing and fermion mass hierarchy in the SO(10) GUT
We give an explanation of both the fermion mass hierarchy and the large lepton mixing angles in the context of a grand unified flavor and gauge theory (GUTF). Starting from an (SU(3) ? U(1))F flavor


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
Permutation symmetries and the fermion mass matrix
We consider SU(2) x U(1) gauge models with an additional global symmetry of S/sub n/ type. In particular, we study S/sub 4/ symmetry for a six-quark--six-lepton standard model. We find that the
U(3)-family nonet Higgs boson and its phenomenology
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
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
Top-quark-mass enhancement in a seesaw-type quark mass matrix
We investigate the implications of a seesawtype mass matrix, i.e.,Mf⋍mLMF−1mR, for quarks and leptonsf under the assumption that the matricesmL andmR are common to all flavors (up-/down- and
Tribimaximal mixing, discrete family symmetries, and a conjecture connecting the quark and lepton mixing matrices
Neutrino oscillation experiments (excluding the LSND experiment) suggest a tri-bimaximal form for the lepton mixing matrix. This form indicates that the mixing matrix is probably independent of the

This paper proposes that for any M one may choose, it should satisfy the condition UMU(T)=M, where U not equal 1 is a specific unitary matrix such that U(N) represents a well-defined discrete symmetry in the nu(e,micro,tau) basis.
