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 quark-/lepton-sectors) and the matricesMF characterizing the heavy fermion sectors have the form [(unit matrix)+bf (a democratic matrix)] wherebf is a flavor parameter. We find that by adjusting the complex parameterbf, the model can provide thatmt≫mb while at the same time keepingmu∼md without assuming any…

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
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

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
