The thermal relic abundance of Dark Matter motivates the existence of new electroweak scale particles, independent of naturalness considerations. However, most un- natural Dark Matter models do not ensure the presence of new particles charged under SU(3)C, resulting in challenging LHC phenomenology. Here, we present a class of models with scalar electroweak doublet Dark Matter that require a host of colored particles at the TeV scale. In these models, the Higgs boson is apparently fine-tuned, but the Dark Matter doublet is kept light without any additional fine-tuning.

Because of the speciﬁc decay modes considered in the analysis, the bound mH+ > 79.3GeV on the mass of a charged higgs from LEP [18] can not be applied to this model. In [19], the constraint mH+∼>70−90 GeV was derived using the results of the OPAL collaboration [20].”
