Residual flavor symmetry breaking in the landscape of modular flavor models
- Physics
- 2022
We study a symmetry breaking of residual flavor symmetries realized at fixed points of the moduli space. In the supersymmetric modular invariant theories, a small departure of the modulus from fixed…

We present a detailed analysis of the eclectic flavor structure of the two-dimensional Z2 orbifold with its two unconstrained moduli T and U as well as SL(2,Z)T × SL(2,Z)U modular symmetry. This…

Modular symmetry anomaly and nonperturbative neutrino mass terms in magnetized orbifold models
- PhysicsPhysical Review D

We study the modular symmetry anomaly in magnetized orbifold models. The nonperturbative effects such as D-brane instanton effects can break tree-level symmetry. We study which part of the modular…

We study the spontaneous CP violation through the stabilization of the modulus τ in modular invariant flavor models. The CP-invariant potential has the minimum only at Re[τ]=0 or 1/2(mod 1). From…

We study the modular symmetry in magnetized D-brane models on $T^2$. Non-Abelian flavor symmetry $D_4$ in the model with magnetic flux $M=2$ (in a certain unit) is a subgroup of the modular symmetry.…
