Description

We study the minimal type-III seesaw model to explain the origin of the
non-zero neutrino masses and mixing. We show that the naturalness arguments
and the bounds from lepton flavor violating decay (μ → eγ) provide very
stringent bounds on the model along with the constraints on the stability
of the electroweak vacuum up to High energy scale. We perform a detailed
analysis of the model parameter space including all the constraints for both
normal as well as inverted hierarchies of the light neutrino masses. We find
that most of the region that are allowed by lepton flavor violating decay fall
into the metastable region.
