# Scotogenic dark matter stability from gauged matter parity

## TL;DR

This paper proposes a new theoretical framework where dark matter stability is naturally explained by a matter-parity symmetry emerging from the spontaneous breaking of an extended gauge symmetry involving SU(3), SU(3)_L, and U(1) groups with gauged B-L, leading to a scotogenic dark matter model.

## Contribution

It introduces a novel gauge symmetry-based mechanism for dark matter stability, connecting it to spontaneous symmetry breaking and matter parity within an extended electroweak model.

## Key findings

- Dark matter stability arises from gauged matter parity.
- Constructs a consistent scotogenic dark matter model within the extended gauge framework.
- Analyzes the main features and implications of the model.

## Abstract

We explore the idea that dark matter stability results from the presence of a matter-parity symmetry, arising naturally as a consequence of the spontaneous breaking of an extended $\mathrm{SU(3) \otimes SU(3)_L \otimes U(1)_X \otimes U(1)_{N}}$ electroweak gauge symmetry with fully gauged B-L. Using this framework we construct a theory for scotogenic dark matter and analyze its main features.
