Naturality, unification and dark matter

TL;DR

This paper proposes a non-supersymmetric model with Technicolor-driven electroweak symmetry breaking, achieving gauge coupling unification and providing a viable dark matter candidate consistent with cosmological and experimental constraints.

Contribution

It introduces a minimal Technicolor-based model with additional Weyl fermions that unify gauge couplings and include a potential dark matter particle, addressing hierarchy and naturality issues.

Findings

Relic density calculations support dark matter viability.

Model achieves gauge coupling unification at one-loop level.

Hierarchy and naturality problems are addressed without supersymmetry.

Abstract

We consider a model where electroweak symmetry breaking is driven by Technicolor dynamics with minimal particle content required for walking coupling and saturation of global anomalies. Furthermore, the model features three additional Weyl fermions singlet under Technicolor interactions, which provide for a one-loop unification of the Standard Model gauge couplings. Among these extra matter fields exists a possible candidate for weakly interacting dark matter. We evaluate the relic densities and find that they are sufficient to explain the cosmological observations and avoid the experimental limits from earth-based searches. Hence, we establish a non-supersymmetric framework where hierarchy and naturality problems are solved, coupling constant unification is achieved and a plausible dark matter candidate exists.
