Theoretical Model Explores Baryogenesis from Flavor Symmetry Breaking

A new theoretical preprint proposes a minimal realization of the Froggatt-Nielsen mechanism, linking the Standard Model flavor puzzle to spontaneous baryogenesis. The model suggests that if a global U(1)H symmetry breaks before inflation ends, it could generate a pseudo-Nambu-Goldstone boson, leading to spontaneous CPT violation in the Standard Model. This preliminary work, not yet peer-reviewed, offers a new perspective on matter-antimatter asymmetry.
