Dirac gaugino from grand gauge-Higgs unification
Hiroaki Nakano, Masamichi Sato, Osamu Seto +1
We show that models of the Dirac gaugino can naturally be embedded into a kind of the grand unified theory (GUT), the grand gauge-Higgs unification (gGHU) model, with the gauge gro…
Charged Lepton Mass Relations in a SUSY Scenario
Yoshio Koide, Toshifumi Yamashita
The observed charged lepton masses satisfy the relations and $κ\equiv \sqrt{m_e m_μm_τ}/(\sqrt{m_e} +\sqrt{m_μ…
The Standard Model Gauge Symmetry from Higher-Rank Unified Groups in Grand Gauge-Higgs Unification Models
Kentaro Kojima, Kazunori Takenaga, Toshifumi Yamashita
We study grand unified models in the five-dimensional space-time where the extra dimension is compactified on . The spontaneous breaking of unified gauge symmetries is ach…
Gauge Symmetry Breaking Patterns in an SU(5) Grand Gauge-Higgs Unification
Kentaro Kojima, Kazunori Takenaga, Toshifumi Yamashita
We study gauge symmetry breaking patterns of the five-dimensional grand gauge-Higgs unification compactified on an orbifold with the Hosotani mechanism…
term and supersymmetry breaking from six dimensional theory
Yuki Adachi, Naoyuki Haba, Toshifumi Yamashita
We propose a new next-to-minimal supersymmetric standard model (NMSSM) which is on a six-dimensional spacetime compactified on a orbifold. In this model, three gauge sing…
Higgs as a Probe of Supersymmetric Grand Unification with the Hosotani Mechanism
Mitsuru Kakizaki, Shinya Kanemura, Hiroyuki Taniguchi +1
The supersymmetric grand unified theory where the SU(5) gauge symmetry is broken by the Hosotani mechanism predicts the existence of adjoint chiral superfields whose masses are at…
A Unified Description of Quark and Lepton Mass Matrices in a Universal Seesaw Model
Yoshio Koide, Hideo Fusaoka
In the democratic universal seesaw model, the mass matrices are given by \bar{f}_L m_L F_R + \bar{F}_L m_R f_R + \bar{F}_L M_F F_R (f: quarks and leptons; F: hypothetical heavy fer…
Lepton Flavor Violating Z Decays in the Zee Model
Ambar Ghosal, Yoshio Koide, Hideo Fusaoka
We calculate lepton flavor violating (LFV) Z decays Z \to {e_i^\pm}e_j^\mp (i, j = e, μ, τ; i\neq j) in the Zee model keeping in view the radiative leptonic decays e_i\to e_jγ(i =…
Evolution of the Yukawa coupling constants and seesaw operators in the universal seesaw model
Yoshio Koide, Hideo Fusaoka
The general features of the evolution of the Yukawa coupling constants and seesaw operators in the universal seesaw model with det M_F=0 are investigated. Especially, it is checked…
Updated Estimate of Running Quark Masses
Hideo Fusaoka, Yoshio Koide
Stimulated by recent development of the calculation methods of the running quark masses and renewal of the input data, for the purpose of making a standard table of $m_q(μ…
Updated Running Quark Mass Values
Hideo Fusaoka, Yoshio Koide
The running quark masses at various energy scales are evaluated by using the mass renormalization equations systematically. Also, those at energy scales higher than m_Z are evaluat…
Analytical Expressions of Masses and Mixings in a Democratic Seesaw Mass Matrix Model
Yoshio Koide, Hideo Fusaoka
On the basis of a seesaw-type mass matrix model for quarks and leptons , analytical expressions of the masses and mixings of the fermions are in…
Top Quark Mass Enhancement in a Seesaw-Type Quark Mass Matrix
Y. Koide, H. Fusaoka
We investigate the implications of a seesaw type mass matrix, i.e., , for quarks and leptons under the assumption that the matrices and …

H. Fusaoka, Y. Koide
A quark mass matrix model is proposed where and is a unit matrix plus a rank one matri…
