Flavor and CP from String Theory

Modular transformations of string theory are shown to play a crucial role in the discussion of discrete flavor symmetries in the Standard Model. They include CP transformations and provide a…

Residual flavor symmetry breaking in the landscape of modular flavor models

Abstract 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…

The framework of compactified heterotic string theory offers consistent ultraviolet (UV) comple-tions of the Standard Model (SM) of particle physics. In this approach, the existence of flavor symmetries…

Generalized Matter Parities from Finite Modular Symmetries

Completing the eclectic flavor scheme of the ℤ2 orbifold

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

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…
