Universal Seesaw and $0\nu \beta \beta$ in new 3331 left-right symmetric model

Abstract

We consider a class of left-right symmetric model with enlarged gauge group $SU(3{)}_c\times SU(3{)}_L\times SU(3{)}_R\times U(1{)}_X$ without having scalar bitriplet. In the absence of scalar bitriplet, there is no Dirac mass term for fermions including usual quarks and leptons. We introduce new isosinglet vector-like fermions so that all the fermions get their masses through a universal seesaw mechanism. We extend our discussion to neutrino mass and its implications in neutrinoless double beta decay ($0\nu \beta \beta$). We show that for TeV scale $SU(3{)}_R$ gauge bosons, the heavy-light neutrino mixing contributes dominantly to $0\nu \beta \beta$ that can be observed at ongoing experiments. Towards the end we also comment on different possible symmetry breaking patterns of this enlarged gauge symmetry to that of the standard model.
