Viable dark matter via radiative symmetry breaking in a Higgs portal extension of the standard model

We consider generation of dark matter mass via radiative electroweak symmetry breaking in an extension of the conformal Standard Model containing a singlet scalar field with a Higgs portal interaction. Generating the mass from a sequential process of radiative electroweak symmetry breaking followed by a conventional Higgs mechanism can account for less than 30\% of the cosmological dark matter abundance. However in a dynamical approach where both Higgs and scalar singlet masses are generated via radiative electroweak symmetry breaking we obtain much higher levels of dark matter abundance: 10\%--80\% for a dark matter mass of $80\,{\rm GeV}
