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…
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…
Large and small hierarchies from finite modular symmetries
Tetsutaro Higaki, Junichiro Kawamura, Tatsuo Kobayashi +2
We study the moduli stabilization by the radiative corrections due to the moduli dependent vector-like masses invariant under the finite modular symmetry. The radiative stabilizati…
Moduli stabilization and light axion by Siegel modular forms
Shuta Funakoshi, Junichiro Kawamura, Tatsuo Kobayashi +2
We discuss the stabilization of multiple moduli by utilizing Siegel modular forms in the framework of modular invariant theories. We derive the stationary condi…
Spontaneous CP violation and partially broken modular flavor symmetries
Tetsutaro Higaki, Tatsuo Kobayashi, Kaito Nasu +1
We study the realization of spontaneous CP violation through moduli stabilization. In modular flavor models, the source of CP violation is the vacuum expectation values of the comp…
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…
