Inverse Seesaw Neutrino Mass from Lepton Triplets in the U(1)Sigma Model
Abstract
The inverse seesaw mechanism of neutrino mass, i.e. mnu = (mD2/mN2)epsilonL where epsilonL is small, is discussed in the context of the U(1)Sigma model. This is a gauge extension of the Standard Model of particle interactions with lepton triplets (Sigma+,Sigma),Sigma-) as (Type III) seesaw anchors for obtaining small Majorana neutrino masses.
