Neutrinoless double beta decay in Left-Right symmetric model with double seesaw mechanism

Abstract

We discuss a left-right (L-R) symmetric model with the double seesaw mechanism at the TeV scale generating Majorana masses for the active left-handed (LH) flavour neutrinos ${\nu }_{\alpha L}$ and the heavy right-handed (RH) neutrinos $N_{\beta R}$, $\alpha ,\beta =e,\mu ,\tau$, which in turn mediate lepton number violating processes, including neutrinoless double beta decay. The Higgs sector is composed of two Higgs doublets $H_L$, $H_R$, and a bi-doublet $\Phi$. The fermion sector has the usual for the L-R symmetric models quarks and leptons, along with three $SU(2)$ singlet fermion $S_{\gamma L}$. The choice of bare Majorana mass term for these sterile fermions induces large Majorana masses for the heavy RH neutrinos leading to two sets of heavy Majorana particles $N_j$ and $S_k$, $j,k=1,2,3$, with masses $m_{N_j}\ll m_{S_k}$. Working with a specific version of the model in which the ${\nu }_{\alpha L}-N_{\beta R}$ and the $N_{\beta R}-S_{\gamma L}$ Dirac mass terms are diagonal, and assuming that $m_{N_j}\sim (1-1000)$ GeV and $\max (m_{S_k})\sim (1-10)$ TeV, $m_{N_j}\ll m_{S_k}$, we study in detail the new ``non-standard'' contributions to the $0\nu \beta \beta$ decay amplitude and half-life arising due to the exchange of virtual $N_j$ and $S_k$. We find that in both cases of NO and IO light neutrino mass spectra, these contributions are strongly enhanced and are dominant at relatively small values of the lightest neutrino mass $m_{1(3)}\sim (10^{-4}-10^{-2})$ eV over the light Majorana neutrino exchange contribution. In large part of the parameter space, the predictions of the model for the $0\nu \beta \beta$ decay generalised effective Majorana mass and half-life are within the sensitivity range of the planned next generation of neutrinoless double beta decay experiments LEGEND-200 (LEGEND-1000), nEXO, KamlAND-Zen-II, CUPID, NEXT-HD.
