Linear seesaw model with hidden gauge symmetry
Linear seesaw model with hidden gauge symmetry
We propose a natural realization of a linear seesaw model with hidden gauge symmetry in which $SU(2{)}_{L}$ triplet fermions and one extra Higgs singlet, doublet, and quartet scalar are introduced. Small neutrino mass can be realized by two suppression factors that are the small vacuum expectation value of a quartet …
