Abstract
We consider a version of Left-Right Symmetric Model in which the scalar sector consists of a Higgs bidoublet (\(\varPhi \)) with \(B-L=0\), doublets (\(H_{L,R}\)) with \(B-L=1\) and a charged scalar (\(\delta ^+\)) with \(B-L=2\) leading to radiatively generated Majorana masses for neutrinos and thereby, leads to new physics contributions to neutrinoless double beta decay (\(0\nu \beta \beta \)) saturating the present experimental bounds. We show that such a novel framework can be embedded in a non-SUSY SO(10) GUT leading to successful gauge coupling unification at around \(10^{16}\) GeV with the scale of left-right symmetry breaking around \(10^{10}\) GeV. The model can also be extended to have left-right symmetry breaking at TeV scale, enabling detection of \(W_R, Z_R\) bosons in LHC and future collider searches.
