Description
The hierarchical structure of fermion masses and mixings suggests the presence of an underlying mechanism, for which many ideas have been put forward. In this talk, I present a systematic framework to explore such mechanisms from a "global" perspective, as developed in recent studies of the Froggatt-Nielsen mechanism in the quark and lepton sectors (arXiv:2306.08026, 2501.00629). This global approach offers phenomenological insights, testable predictions, and may help set the stage for broader connections to other open problems in particle physics.
