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 unification of CP with traditional flavor symmetries within the framework of the “eclectic flavor” scheme. The unified flavor group is non-universal in moduli space and exhibits the phenomenon of “Local Flavor Unification”, where different sectors of the theory (like quarks and leptons) can be subject to…

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…

We study the lepton flavor models, whose flavor symmetries are finite subgroups of the modular group such as $S_3$ and $A_4$. In our models, couplings are also nontrivial representations of these…
From strings to the MSSM
We review recent progress in embedding the supersymmetric standard model into string theory. We discuss how, with the incorporation of certain aspects of grand unification, a search strategy can be…

Δ(54) flavor phenomenology and strings
A bstractΔ(54) can serve as a flavor symmetry in particle physics, but remains almost unexplored. We show that in a classification of semi-realistic ℤ3 × ℤ3 heterotic string orbifolds, Δ(54) turns…
