Stringy Constraints on Modular Flavor Models
Keiya Ishiguro, Takafumi Kai, Tatsuo Kobayashi +1
We investigate stringy constraints on moduli spaces in modular flavor models by analyzing moduli-dependent threshold corrections in heterotic string vacua. While moduli play a cruc…

Classification of Modular Symmetries in Type IIB Flux Landscape
Keiya Ishiguro, Takafumi Kai, Tatsuo Kobayashi +2
In this work, we study modular symmetries in type IIB flux landscape by investigating symplectic basis transformations of period vectors on toroidal orbifolds. To fix explicit cycl…

Flux Landscape with Enhanced Symmetry Not on Elliptic Points
Keiya Ishiguro, Takafumi Kai, Tatsuo Kobayashi +1
We study structures of solutions for SUSY Minkowski F-term equations on two toroidal orientifolds with . Following our previous study \cite{Ishiguro:2020tmo}, with fi…
