Cascade Hierarchy in SUSY SU(5) GUT
Kentaro Kojima, Hideyuki Sawanaka, Ryo Takahashi
We study cascade hierarchy in supersymmetric SU(5) grand unified theory. The neutrino Dirac mass matrix of the cascade form can lead to the tri-bimaximal generation mixing at the l…
Probing neutrino masses and tri-bimaximality with lepton flavor violation searches
Kentaro Kojima, Hideyuki Sawanaka
We examine relation between neutrino oscillation parameters and prediction of lepton flavor violation, in light of deviations from tri-bimaximal mixing. Our study shows that upcomi…
New Approach to Texture-zeros with S_3 symmetry - Flavor Symmetry and Vacuum Aligned Mass Textures -
Satoru Kaneko, Hideyuki Sawanaka, Takaya Shingai +2
A texture-zeros is an approach to reduce the number of free parameters in Yukawa couplings and it is one of the most attractive ones. In our paper, we discuss the origin of zero-st…
Quark and lepton mass matrices with family symmetry
H. Sawanaka
Realistic quark masses and mixing angles are obtained applying the successful family symmetry for leptons, motivated by the quark-lepton assignments of SU(5). The symme…
Higgs Potential and Texture-zeros in Supersymmetric Standard Model
Satoru Kaneko, Hideyuki Sawanaka, Takaya Shingai +2
The mass matrix forms of quarks and leptons are discussed in theory with permutation flavor symmetry. The structure of scalar potential is analyzed in case that electroweak doublet…
Mass Splitting of Staggered Fermion and Clifford Algebra
M. Hatakeyama, H. Sawanaka, H. So
We present a new method to introduce rotationally invariant terms in staggered fermions which is based on an Clifford algebra formulation, where means the number of sp…
