Challenge to the Mystery of the Charged Lepton Mass Formula
Yoshio Koide
Why the charged lepton mass formula m_e +m_μ+m_τ= {2/3} (\sqrt{m_e}+\sqrt{m_μ} +\sqrt{m_τ})^2 is mysterious is reviewed, and guiding principles to solve the mystery are presented.…
Quark and Lepton Mass Matrix Structures Suggested by the Observed Unitary Triangle Shape
Yoshio Koide
Under the hypothesis that the CP violating phase parameter δin the CKM matrix V takes own value so that the radius R(δ) of the circle circumscribed about the unitary triangle takes…
Comments on a Flavor Symmetry
Yoshio Koide
It is pointed out that if a flavor symmetry (a discrete symmetry, a U(1) symmetry, and so on) exists, we cannot obtain the observed CKM quark mixing matrix V_q and MNS lepton mixin…
An SU(5) SUSY Model with R-Parity Violation and Radiatively Induced Neutrino Masses
Yoshio Koide, Joe Sato
The radiatively induced neutrino mass matrix is investigated on the basis of an SU(5) SUSY model. In order to evade the proton decay, an ansatz based on a discrete symmetry i…
Quark and Lepton Mass Matrices with a Cyclic Permutation Invariant Form
Yoshio Koide
As an attempt to give an unified description of quark and lepton mass matrices M_f, the following mass matrix form is proposed: the form of the mass matrices are invariant under a…
Universal Seesaw Mass Matrix Model and Neutrino Phenomenology
Yoshio Koide
Stimulated by the recent development of the ``universal seesaw mass matrix model", an application of the model to the neutrino mass matrix is investigated: For the charged lepton a…
