Quantum aspects of non-invertible flavor symmetries in intersecting/magnetized D-brane models
Shuta Funakoshi, Tatsuo Kobayashi, Hajime Otsuka
We discuss selection rules of chiral matters in type IIA intersecting and IIB magnetized D-brane models on toroidal orbifolds. Since the chiral matters on toroidal orbifolds are la…
Modular symmetry of localized modes
Tatsuo Kobayashi, Hajime Otsuka, Shohei Takada +1
We study the modular symmetry of localized modes on fixed points of orbifold. First, we find that the localized modes with even (odd) modular weight generally ha…
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…
Yukawa textures from non-invertible symmetries
Tatsuo Kobayashi, Hajime Otsuka, Morimitsu Tanimoto
Phenomenological aspects of non-invertible symmetries, in particular the flavor structure of quarks and leptons, are studied. We start with a discrete symmetry and g…
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…
Non-invertible flavor symmetries in magnetized extra dimensions
Tatsuo Kobayashi, Hajime Otsuka
We discuss non-invertible symmetries in toroidal compactifications of higher dimensional Yang-Mills theory with magnetic fluxes, which can be regarded as an effective action of typ…
