Investigation of dark matter in minimal 3-3-1 models

Abstract

We show that the 3-3-1 model with minimal lepton content can work as a 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, and we determine the parameter spaces in the WMAP-allowed region of relic density. Indirect and direct searches for dark matter in both cases are investigated by using micrOMEGAs.
