Flavors of Quarks/Leptons in Modular Symmetry

We review the modular group and the recent progress on the modular flavor symmetry of quarks and leptons. We present an example of the modular invariant flavor model by using the Level 3 modular group, which is isomorphic to A4. In the model of flavors, both CP and modular symmetry are broken sponta...

Summary:We review the modular group and the recent progress on the modular flavor symmetry of quarks and leptons. We present an example of the modular invariant flavor model by using the Level 3 modular group, which is isomorphic to A4. In the model of flavors, both CP and modular symmetry are broken spontaneously by the vacuum expectation value of the modulus τ at close to the fixed point.
