Abstract

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.
