EWSB from the soft portal into Dark Matter and prediction for direct detection

Scalar Dark Matter (DM) can have dimensionful coupling to the Higgs boson - the "soft" portal into DM - which is predicted to be unsuppressed by underlying SO(10) GUT. The dimensionful coupling can be large, \mu/v >> 1, without spoiling perturbativity of low energy theory up to the GUT scale. We show that the soft portal into DM naturally triggers radiative EWSB via large 1-loop DM corrections to the effective potential. In this scenario EWSB, DM thermal freeze-out cross section and DM scattering on nuclei are all dominated by the same coupling, predicting DM mass range to be 700 GeV< M_{DM} < 2 TeV. 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.
