Finite modular subgroups for fermion mass matrices and baryon/lepton number violation
Tatsuo Kobayashi, Yusuke Shimizu, Kenta Takagi +3
We study a flavor model that the quark sector has the modular symmetry,while the lepton sector has the modular symmetry. Our model leads to characteristic quark mass ma…
Modular invariance and neutrino mixing
Tatsuo Kobayashi, Naoya Omoto, Yusuke Shimizu +3
We study the phenomenological implications of the modular symmetry of lepton flavors facing recent experimental data of neutrino oscillations. The mass matrices o…
Towards the minimal seesaw model for the prediction of neutrino CP violation
Yusuke Shimizu, Kenta Takagi, Morimitsu Tanimoto
We discuss the minimal seesaw model for the Dirac CP violating phase of the lepton mixing matrix. We introduce two right-handed Majorana neutrinos and obtain several textures of th…
Revisiting model for leptons in light of NuFIT 3.2
Sin Kyu Kang, Yusuke Shimizu, Kenta Takagi +2
We revisit the model for leptons in light of new result of NuFIT 3.2. We introduce a new flavon transforming as singlet or which couples to both charged l…
Effective theory analysis for vector-like quark model
Takuya Morozumi, Yusuke Shimizu, Shunya Takahashi +1
We study a model with a down-type SU(2) singlet vector-like quark (VLQ) as a minimal extension of the standard model (SM). In this model, flavor changing neutral currents (FCNCs) a…
