Generation structures and Yukawa couplings in magnetized models
Tim Jeric, Tatsuo Kobayashi, Kaito Nasu +1
We study fermion zero-mode wave functions with various chiralities in magnetized , torus. First, we consider the wave functions satisfying the Dirac equation and…
On discrete gauging and non-invertible selection rules
Jun Dong, Tim Jeric, Tatsuo Kobayashi +2
We clarify selection rules of conjugacy classes of several finite discrete groups where we deal with both gauged and ungauged cases. We find that the selection rules enjoy finite A…
Flavor symmetries from modular subgroups in magnetized compactifications
Tatsuo Kobayashi, Kaito Nasu, Ryusei Nishida +2
We study the flavor structures of zero-modes, which are originated from the modular symmetry on and its orbifold with magnetic fluxes. We introduce the constrai…
Moduli stabilization in finite modular symmetric models
Yoshihiko Abe, Komei Goto, Testutaro Higaki +2
We study vacua of moduli potential consisting of multiple contribution of modular forms in a finite modular symmetry. If the potential is given by a single modular form, the Minkow…

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…

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…
Radiative correction on moduli stabilization in modular flavor symmetric models
Tatsuo Kobayashi, Kaito Nasu, Riku Sakuma +1
We study the radiative corrections to the stabilization of the complex structure modulus in modular flavor symmetric models. We discuss the possibility of obtaining the vacuum…
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…
