We present a revised version of the so-called “yukawaon model”, which was proposed for the purpose of a unified description of the lepton mixing matrix UPMNS and the quark mixing matrix VCKM. It is assumed from a phenomenological point of view that the neutrino Dirac mass matrix MD is given with a somewhat different structure from the charged lepton mass matrix Me, although MD=Me was assumed in the previous model. As a result, the revised model predicts a reasonable value sin22θ13∼0.07 with…

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
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
Neutrino mass matrix model with a bilinear form
A bstractA neutrino mass matrix model with a bilinear form $ {M_{\nu }}={k_{\nu }}{{\left( {{M_D}M_R^{-1 }M_D^T} \right)}^2} $ is proposed within the framework of the so-called yukawaon model, which
Unified Lepto-Quark Mixing
We describe a solution to a long standing puzzle about the difference in textures of quark CKM and lepton PMNS mixing matrices by deriving their common representation. We show how the difference in
Yukawaon Model with Anomaly Free Set of Quarks and Leptons in a U(3) Family Symmetry
In the so-called "yukawaon" model, the (effective) Yukawa coupling constants $Y_f^{eff}$ are given by vacuum expectation values (VEVs) of scalars $Y_f$ (yukawaons) with $3\times 3$ components. So
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

Unified description of quark and lepton mixing matrices based on a yukawaon model
Based on a supersymmetric Yukawaon model with O(3) family symmetry, possible forms of quark and lepton mixing matrices are systematically investigated under a condition that the up-quark mass matrix

On the basis of the so-called “yukawaon” model, we found a special form of the neutrino mass matrix Mν which gives reasonable predictions. The Mν is given by a multiplication form made of charged
