We take the stealth model,1 an inert [Formula: see text] multiplet of real scalar singlets, as a candidate for dark matter. We limit the parameter space on the basis of dark matter abundance and direct search experiments. Further we study briefly a real scalar triplet as dark matter candidate. Then a two-component dark matter model is considered, which consists of a real scalar singlet and a scalar triplet with a Z2×Z2 symmetry. In a narrow mass range, the direct search experiments start to give some limitations.

Abstract We propose a vector dark matter model with an exotic dark SU(2) gauge group. Two Higgs triplets are introduced to spontaneously break the symmetry. All of the dark gauge bosons become massive, and the lightest one is a viable vector DM candidate. Its stability is guaranteed by a remaining Z2 symmetry. We study the parameter space constrained by the Higgs measurement data, the dark matter relic density, and direct and indirect detection experiments. We find numerous parameter points satisfying all the constraints, and they could be further tested in future experiments. Similar methodology can be used to construct vector dark matter models from an arbitrary SO(N) gauge group.
