Dark Matter in the Simplest Little Higgs Model

Abstract

We investigate a variation of the Simplest Little Higgs (SLH) model that is invariant under a discrete ${\text{CZ}}_2$ symmetry. Our motivation for imposing this symmetry is the two dark matter candidates it implies, a scalar $\eta$ and a heavy neutrino. We examine the viability of these two candidates using the standard relic abundance calculation. Direct detection prospects are also discussed.
