Neutrino masses and mixing from S4 flavor twisting
Hajime Ishimori, Yusuke Shimizu, Morimitsu Tanimoto +1
We discuss a neutrino mass model based on the S4 discrete symmetry where the symmetry breaking is triggered by the boundary conditions of the bulk right-handed neutrino in the fift…
Deviations from Tri-Bimaximality and Quark-Lepton Complementarity
Yusuke Shimizu, Ryo Takahashi
We study deviations from tri-bimaximality (TBM) and quark-lepton complementarity (QLC) in a model independent way. The current neutrino experimental data is well approximated by tr…
Tri-bimaximal Mixing and Cabibbo Angle in S4 Flavor Model with SUSY
Hajime Ishimori, Kouta Saga, Yusuke Shimizu +1
We present a flavor model of quarks and leptons with the non-Abelian discrete symmetry in the framework of the SU(5) SUSY GUT. Three generations of -plets in SU(5) ar…
Non-Abelian Discrete Symmetries in Particle Physics
Hajime Ishimori, Tatsuo Kobayashi, Hiroshi Ohki +3
We review pedagogically non-Abelian discrete groups, which play an important role in the particle physics. We show group-theoretical aspects for many concrete groups, such as repre…
