WIMPs in a 3-3-1 model with heavy Sterile neutrinos

TL;DR

This paper explores a 3-3-1 gauge model with heavy sterile neutrinos, identifying potential WIMP dark matter candidates, calculating their relic abundance, and assessing their detectability in experiments like CDMS-II, with implications for the model's symmetry breaking scale.

Contribution

It introduces a novel 3-3-1 model framework that predicts up to three WIMP candidates and analyzes their relic abundance and experimental detectability.

Findings

Up to three WIMP dark matter candidates identified.

Relic abundance calculations consistent with observed dark matter.

Strong bounds on symmetry breaking scale above 3 TeV.

Abstract

In this work we show that from the spectrum of particles of a 3-3-1 gauge model with heavy sterile neutrinos we can have up to three Cold Dark Matter candidates as WIMPs. We obtain their relic abundance and analyze their compatibility with recent direct detection experiments, exploring the possibility of explaining the two events reported by CDMS-II. An interesting outcome of this 3-3-1 model, concerning direct detection of two WIMPs in the model, is a strong bound on the symmetry breaking scale, which imposes it to be above 3 TeV.
