Scale Invariant Extension of the Standard Model with a hidden QCD-like Sector

TL;DR

This paper proposes a scale-invariant extension of the Standard Model incorporating a hidden QCD-like sector, where electroweak symmetry breaking occurs dynamically and hidden-QCD pions serve as dark matter candidates.

Contribution

It introduces a novel scale-invariant model with a hidden QCD sector that dynamically generates electroweak symmetry breaking and provides a dark matter candidate.

Findings

Electroweak symmetry breaking is dynamically generated.

Hidden-QCD pions are stable and potential dark matter candidates.

The model maintains scale invariance and asymptotic freedom.

Abstract

A scale-invariant extension of the Standard Model with a singlet-scalar and hidden-QCD sector is studied. The scale of electroweak symmetry breaking is generated dynamically in an asymptotic-free hidden-QCD sector, and mediated by the Higgs-singlet coupling. Hidden-QCD pions are stable and can be a candidate of the cold dark matter. This presentation is based on a collaboration with D. W. Jung and P. Ko.
