Modular Origin of Mass Hierarchy: Froggatt-Nielsen like Mechanism
Hitomi Kuranaga, Hiroshi Ohki, Shohei Uemura
We study Froggatt-Nielsen (FN) like flavor models with modular symmetry. The FN mechanism is a convincing solution to the flavor puzzle in quark sector. The FN mechanism requires a…
Majorana neutrino masses by D-brane instanton effects in magnetized orbifold models
Kouki Hoshiya, Shota Kikuchi, Tatsuo Kobayashi +3
We study Majorana neutrino masses induced by D-brane instanton effects in magnetized orbifold models. We classify possible cases, where neutrino masses can be induced. Three and fo…
Modular Flavor Symmetry on Magnetized Torus
Hiroshi Ohki, Shohei Uemura, Risa Watanabe
We study the modular invariance in magnetized torus models. Modular invariant flavor model is a recently proposed hypothesis for solving the flavor puzzle, where the flavor symmetr…
Loop Fayet-Iliopoulos terms in models: instability and moduli stabilization
Hiroyuki Abe, Tatsuo Kobayashi, Shohei Uemura +1
We study Fayet-Iliopoulos (FI) terms of six-dimensional supersymmetric Abelian gauge theory compactified on a orbifold. Such orbifold compactifications can lead to locali…
Revisiting instabilities of models with loop-induced Fayet-Iliopoulos terms
Hiroyuki Abe, Tatsuo Kobayashi, Shohei Uemura +1
We study Fayet-Iliopoulos (FI) terms of 5-dimensional supersymmetric gauge theory compactified on . In this model, loop diagrams including matter hypermultiplets an…
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…
