Probing Dark Matter in the Economical 3-3-1 Model

TL;DR

This paper demonstrates that the economical 3-3-1 model contains a viable dark matter candidate, a scalar particle, with its relic abundance and detection prospects analyzed within experimental constraints.

Contribution

It identifies a specific scalar in the economical 3-3-1 model as a dark matter candidate and evaluates its relic density and detection possibilities.

Findings

The scalar H_1^0 can account for dark matter within TeV mass range.

Parameter space consistent with WMAP relic abundance constraints is identified.

Direct and indirect detection prospects are analyzed for the candidate.

Abstract

We show that the economical 3-3-1 model has a dark mater candidate. It is a real scalar H_1^0 in which main part is bilepton (with lepton number 2) and its mass is in the range of some TeVs. We calculate the relic abundance of H_1^0 dark matter by using micrOMEGAs 2.4 and figure out parameter space satisfying the WMAP constraints. Direct and indirect searches are studied for a special choice of parameters in the WMAP - allowed region.
