Dark matter in a charged variant of the Scotogenic model

TL;DR

This paper explores a charged variant of the Scotogenic model, focusing on its dark matter candidate, which is bosonic, and investigates how new charged states affect its phenomenology and compatibility with observations.

Contribution

It introduces a novel charged variant of the Scotogenic model and analyzes its dark matter candidate, highlighting differences from the original model and potential new parameter space.

Findings

Bosonic dark matter candidate is viable in this model.

New charged states expand the parameter space.

Model remains compatible with current observations.

Abstract

Scotogenic models are among the most elegant and economic solutions that provide an explanation for two of the main open questions in particle physics: neutrino masses and dark matter (DM). In this work, after a brief discussion of the model, we present a phenomenological study of the DM candidate in a variant of the Scotogenic model. While in the original Scotogenic scenario the DM candidate can be fermionic or bosonic, only the latter is viable in this version. The presence of new charged states might reveal new regions in the parameter space compatible with current observations.
