Predicting charged lepton flavor violation from 3-3-1 gauge symmetry

Understand

The simplest realization of the inverse seesaw mechanism in a $SU(3)_C \otimes SU(3)_L \otimes U(1)_X$ gauge theory offers striking flavor correlations between rare charged lepton flavor violating decays and the measured neutrino oscillations parameters.

• The predictions follow from the gauge structure itself without the need for any flavor symmetry.
• Such tight complementarity between charged lepton flavor violation and oscillations renders the scenario strictly testable.
