A Simple Realization of the Inverse Seesaw Mechanism
arXiv:1206.2590 · doi:10.1103/PhysRevD.86.035007
Abstract
Differently from the canonical seesaw mechanism, which is grounded in grand unified theories, the inverse seesaw mechanism lacks a special framework that realizes it naturally. In this work we advocate that the 3-3-1 model with right-handed neutrinos has such an appropriate framework to accommodate the inverse seesaw mechanism. We also provide an explanation for the smallness of the $μ$ parameter and estimate the branching ratio for the rare lepton flavor violation process $μ\rightarrow eγ$.
