Koide's mass formula is an empirical relation among the charged lepton masses which holds with a striking precision. We present a model of charged lepton sector within an effective field theory with U(3) × SU(2) family gauge symmetry, which predicts Koide's formula within the present experimental accuracy. Radiative corrections as well as other corrections to Koide's mass formula have been taken into account. We adopt a known mechanism, through which the charged lepton spectrum is determined by…

A relaxed version of Koide's mass formula from Yukawaons: classical and SUSY scenarios
We present a relaxed version of Koide's mass formula from a nonet Yukawaon scalar in the $\mathrm{SU}(3)$ flavor symmetry. Koide's character $K$, which involves the Standard Model fermion masses, is
A New Empirical Approach to Quark and Lepton Masses
We present an alternative to the Koide formula and it’s extensions. By introducing two parameters k and ↵f derived from charged leptons we are able to construct new empirical formulas that appear to
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
Yukawaon model with U(3)×O(3) family symmetries
A quark and lepton mass matrix model with family symmetries U(3)×O(3) is investigated on the basis of the so-called Yukawaon model. In the present model, quarks and leptons are assigned to (l, ec,
Sumino's Cancellation Mechanism in an Anomaly-Free Model
An interesting family gauge boson (FGB) model (Model A) has been proposed by Sumino. The model can give FGBs with a considerably low energy scale in spite of the sever constraints form the observed


Solving the SUSY flavour and CP problems with SU(3) family symmetry
We show how the SUSY flavour and CP problems can be solved using gauged SU(3) family symmetry previously introduced to describe quark and lepton masses and mixings, in particular neutrino
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
F-term induced flavor mass spectrum
New mechanism of generating flavor mass spectrum is proposed by using an O'Raifeartaigh-type supersymmetry breaking model. A desired bilinear form of fermion mass spectrum is naturally realized
All three charged lepton pole masses are given to O(10-5) accuracy by $(m_e, m_\mu, m_\tau)=(313.85773~{\rm MeV})[1+\sqrt{2}\,{\rm cos}\,\theta_k]^2$, where θk = 2πk/3 + 2/9 with the generation
Empirical neutrino mass matrix related to up-quark Masses
According to an idea that mass spectra of quarks and leptons originate in vacuum expectation values of 0(3) flavor (3 x 3)s = 1 + 5 (gauge singlet) scalars, a neutrino mass matrix related to up-quark
Neutrinos and SU(3) family gauge symmetry
We include the standard model (SM) leptons in a recently proposed framework for the generation of quark mass ratios and Cabibbo-Kobayashi-Maskawa (CKM) mixing angles from a SU(3) family gauge
Predicting neutrino parameters from SO(3) family symmetry and quark-lepton unification
We show how the neutrino mixing angles and oscillation phase can be predicted from tri-bimaximal neutrino mixing, corrected by charged lepton mixing angles which are related to quark mixing angles
