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…

Quark and lepton mass matrices described by charged lepton masses
Recently, we proposed a unified mass matrix model for quarks and leptons, in which, mass ratios and mixings of the quarks and neutrinos are described by using only the observed charged lepton mass
Quark and lepton mass matrix model with only six family-independent parameters
We propose a unified mass matrix model for quarks and leptons, in which sixteen observables of mass ratios and mixings of the quarks and neutrinos are described by using no family number-dependent
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
Quark sectorCPviolation of the universal seesaw model
We study the CP violation of universal seesaw model, especially its quark sector. The model is based on SU(2)_L \times SU(2)_R \times U(1)_{Y^\prime}. In order to count the number of parameters in
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
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
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
Origin of Hierarchical Structures of Quark and Lepton Mass Matrices
It is shown that the so-called "Yukawaon" model can give a unified description of masses, mixing and $CP$ violation parameters of quarks and leptons without using any hierarchical (family
Flavon VEV Scales in U(3)$\times$U(3)$'$ Model
We have recently proposed a quark and lepton mass matrix model based on U(3)×U(3)′ family symmetry as the so-called Yukawaon model, in which the U(3) symmetry is broken by VEVs of flavons (Φf)iα


The quark mass gap and quark mass hierarchy is obtained by introducing a BCS interaction among ur-quarks. A 3×3 quark mass matrix with equal matrix elements, i.e., with all ur-flavors interacting

Experimental data indicate that CP is nowhere maximally nonconserved and the question of maximal CP nonconservation is discussed.
Evidence for top quark production in p-barp collisions at sqrt s =1.8 TeV.
We summarize a search for the top quark with the Collider Detector at Fermilab (CDF) in a sample of [ital [bar p]p] collisions at [radical][ital s] =1.8 TeV with an integrated luminosity of 19.3
Evidence for top quark production in p p collisions at s = 1.8 TeV
We present the results of a search for the top quark in 19.3 pb−1 of p¯p collisions at √s =1.8 TeV. The data were collected at the Fermilab Tevatron collider using the Collider Detector at Fermilab
CP Violation in the Renormalizable Theory of Weak Interaction
In a framework of the renormalizable theory of weak interaction, problems of CP-violation are studied. It is concluded that no realistic models of CP-violation exist in the quartet scheme without
