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

TL;DR

This paper explores a classically scale-invariant extension of the standard model where a dark non-Abelian gauge symmetry is spontaneously broken, providing a potential origin for the electroweak scale and viable dark matter candidates.

Contribution

It introduces a novel scale-invariant model with a dark gauge sector that explains the electroweak scale and dark matter within a unified framework.

Findings

Dark gauge multiplet can serve as dark matter.

Model parameters exist that produce a viable dark matter candidate.

The Higgs portal links dark sector breaking to electroweak symmetry.

Abstract

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.
