Gauged Flavor Symmetries
Abstract content
In gauging the Standard Model flavor group, anomaly cancellation requires adding fermions. Remarkably their mass is inversely related to the known fermion masses, as in the well known neutrino see-saw. In this case all flavor violating effects turn out to be controlled roughly by the Standard Model Yukawa, suppressing transitions for the light generations. Due to the inverted hierarchy the scale of new gauge flavor bosons could be as low as the electroweak scale. The mechanism of flavor protection potentially provides an alternative to Minimal Flavor Violation, with flavor violating effects suppressed by hierarchy of scales rather than couplings.
