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… Expand

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… Expand

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… Expand

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… Expand

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… Expand
