Scalar dark matter from theory space

The scalar dark matter candidate in a prototypical theory space little Higgs model is investigated. We review all details of the model pertinent to a relic density calculation. We perform a thermal relic density calculation including couplings to the gauge and Higgs sectors of the model. We find two regions of parameter space that give acceptable dark matter abundances. The first region has a dark matter candidate with a mass $O\left(100\mathrm{}\mathrm{GeV}\right),$ the second region has a candidate with a mass greater than $O\left(500\mathrm{}\mathrm{GeV}\right).\mathrm{}$ The dark matter candidate in either region is an admixture of an $\mathrm{SU}\left(2\right)\mathrm{}$ triplet and an $\mathrm{SU}\left(2\right)\mathrm{}$ singlet, thereby constituting a possible weakly interacting massive particle.
