Investigation of Dark Matter in Minimal 3-3-1 Models

TL;DR

This paper explores how minimal 3-3-1 models can incorporate inert scalars as dark matter candidates, analyzing their relic density and detection prospects using computational tools.

Contribution

It demonstrates that minimal 3-3-1 models can naturally include inert scalars as dark matter candidates and studies their phenomenology.

Findings

Identified parameter spaces consistent with WMAP relic density

Analyzed direct detection prospects using micrOMEGAs

Studied both doublet and singlet scalar dark matter candidates

Abstract

It is shown that the 3-3-1 model with the minimal lepton content can work as two-Higgs-triplet 3-3-1 model while leaving the other scalars as inert particles responsible for dark matter. We study two cases of dark matter corresponding to the doublet and singlet scalar candidates. We figure out the parameter spaces in the WMAP allowed region of the relic density. The indirect and direct searches for dark matter in both cases are investigated by using micrOMEGAs.
