Dark matter from a radiative inverse seesaw majoron model

We propose a Majoron-like extension of the Standard Model with an extra global U(1)(X)-symmetry where neutrino masses are generated through an inverse seesaw mechanism at the 1-loop level . In contrast to the tree-level inverse seesaw, our framework contains dark matter (DM) candidates stabilized by a residual Z(2)-symmetry surviving spontaneous breaking of the U(1)(X)-group. We explore the case in which the DM is a Majorana fermion. Furthermore, we provide parameter space regions allowed by current experimental constraints coming from the dark matter relic abundance, (in)direct detection, and charged lepton flavor violation.

Automated summary

In this study, we propose a Majoron-like extension of the Standard Model where neutrino masses are generated through an inverse seesaw mechanism. We explore the case of Majorana fermions as dark matter candidates in this framework. Additionally, we provide parameter space regions that satisfy current experimental constraints.
