Description
We consider a minimal model of GUT scalar dark matter with one complex scalar singlet and one 'inert' doublet from the 16 of non-SUSY SO(10). Both dark matter abundance and direct detection cross section are dominated by the new soft coupling between the SM Higgs boson, the singlet and the doublet. The soft coupling can be large without violating perturbativity below the GUT scale. The electroweak symmetry is broken radiatively by dark matter couplings to the Higgs boson. Demanding perturbativity and vacuum stability up to the GUT scale predicts the mass range on order of 0.1…1 TeV for thermal relic dark matter. The spin-independent direct detection cross section is predicted to be just at the present experimental sensitivity and can explain the observed CDMS II recoil events. The distinctive feature of LHC phenomenology will be a displaced dilepton vertex.
