Inverse seesaw and dark matter in models with exotic lepton triplets

TL;DR

This paper proposes a model with exotic lepton triplets that naturally generates neutrino masses through a radiative inverse seesaw mechanism, predicts new TeV-scale particles, and offers a dark matter candidate testable at the LHC.

Contribution

It introduces a novel model with exotic leptons as triplets that links neutrino mass generation and dark matter stability at the TeV scale.

Findings

Neutrino masses are generated via a radiative inverse seesaw.

Exotic leptons can be detected at the LHC.

A stable dark matter candidate naturally arises from the model.

Abstract

We show that models with exotic leptons transforming as E ~ (1,3,-1) under the standard model gauge symmetry are well suited for generating neutrino mass via a radiative inverse seesaw. This approach realizes natural neutrino masses and allows multiple new states to appear at the TeV scale. The exotic leptons are therefore good candidates for new physics that can be probed at the LHC. Furthermore, remnant low-energy symmetries ensure a stable dark matter candidate, providing a link between dark matter and the origins of neutrino mass.
