Minimal Froggatt-Nielsen textures

A bstract The flavour problem of the Standard Model can be addressed through Froggatt-Nielsen (FN) mechanism. In this work, we develop an approach to study FN textures building a direct link between FN-charge assignments and measured masses mixing angles via unitary transformations in space. We specifically focus on quark sector identify most economic models able provide dynamical natural understanding puzzle. Remarkably, find viable textures, involving charges under horizontal symmetry that do not exceed one absolute value (in units flavon charge). Within our approach, also explore degree tuning solving measure analogous Barbieri-Giudice one. solutions involve peculiar cancellations
