Descripción
Modular symmetries have emerged as a promising and elegant approach to the flavor problem, with the discrete group $A_4$ as a benchmark example. In this work, we study the impact of modular UV interactions generating dimension-6 SMEFT operators with leptons. Restricting to extensions with a single mediator and at most one modular form insertion, we classify the possible scenarios and compute their one-loop matching. We show how charged lepton flavor violating observables provide stringent constraints, offering a systematic path to test modular flavor symmetries in the future.
