CP phase in modular flavor models and discrete Froggatt-Nielsen models
Shota Kikuchi, Tatsuo Kobayashi, Kaito Nasu
We study the large mass hierarchy and CP violation in the modular symmetric quark flavor models without fine-tuning. Mass matrices are written in terms of modular forms. Modular fo…
modular symmetry in flavor structures: quark flavor models and Siegel modular forms for
Shota Kikuchi, Tatsuo Kobayashi, Kaito Nasu +2
We study an approach to construct Siegel modular forms from . Zero-mode wave functions on with magnetic flux background behave Siegel modular forms at the origin. Th…
Modular symmetry in magnetized torus and orbifold models
Shota Kikuchi, Tatsuo Kobayashi, Kaito Nasu +2
We study the modular symmetry in magnetized torus and orbifold models. The torus has the modular symmetry . Magnetic flux background brea…
Moduli trapping mechanism in modular flavor symmetric models
Shota Kikuchi, Tatsuo Kobayashi, Kaito Nasu +1
We discuss how the moduli in modular flavor symmetric models dynamically select enhanced symmetry points at which the residual modular symmetry renders extra matter fields massless…
Zero-modes in magnetized orbifold models through modular symmetry
Shota Kikuchi, Tatsuo Kobayashi, Kaito Nasu +2
We study of fermion zero-modes on magnetized orbifolds. In particular, we focus on non-factorizable orbifolds, i.e. and …
Quark mass hierarchies and CP violation in modular symmetric flavor models
Shota Kikuchi, Tatsuo Kobayashi, Kaito Nasu +2
We study modular symmetric flavor models to realize quark mass hierarchies and mixing angles without fine-tuning. Mass matrices are written in terms of…
