Classical scale-invariance, the electroweak scale and vector dark matter

Understand

We consider a classically scale-invariant extension of the standard model in which a dark, non-Abelian gauge symmetry is spontaneously broken via the Coleman-Weinberg mechanism.

• Higgs portal couplings between the dark and standard model sectors provide an origin for the Higgs mass squared parameter and, hence, the electroweak scale.
• We find that choices for model parameters exist in which the dark gauge multiplet is viable as dark matter.
