Description

Abstract: Modular flavor symmetries offer an attractive framework for addressing the flavor puzzle. In this framework, Yukawa couplings are modular forms, i.e. functions of a single complex modulus, rather than free parameters. In this talk, I will show how fermion mass hierarchies arise naturally in this framework. I will also present invariants built from neutrino observables that are independent of the modulus and essentially immune to renormalization group corrections. These invariants lead to robust predictions that can be tested directly by experiments.
