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…
F-term Moduli Stabilization and Uplifting
Tatsuo Kobayashi, Osamu Seto, Shintaro Takada +3
We study Kähler moduli stabilization in IIB superstring theory. We propose a new moduli stabilization mechanism by the supersymmetry-braking chiral superfield which is coupled to K…
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…
Quark mass matrices in magnetized orbifold models with localized Fayet-Iliopoulos terms
H. Abe, T. Kobayashi, S. Takada +2
We study magnetized orbifold models. We assume the localized Fayet-Iliopoulos terms and the corresponding gauge background. Such terms lead to strong localization of zero-mode wave…
Modular symmetry and non-Abelian discrete flavor symmetries in string compactification
Tatsuo Kobayashi, Satoshi Nagamoto, Shintaro Takada +2
We study the modular symmetry in magnetized D-brane models on . Non-Abelian flavor symmetry in the model with magnetic flux (in a certain unit) is a subgroup of th…
Neutrino mixing from finite modular groups
Tatsuo Kobayashi, Kentaro Tanaka, Takuya H. Tatsuishi
We study the lepton flavor models, whose flavor symmetries are finite subgroups of the modular group such as and . In our models, couplings are also nontrivial represent…
