Dynamical generation of the weak and Dark Matter scale

TL;DR

This paper proposes a minimal extension to the Standard Model where the weak and Dark Matter scales are dynamically generated, predicting a new scalar detectable at colliders and gravitational waves from phase transitions.

Contribution

It introduces a simple model that links the weak scale and Dark Matter stability without relying on quadratic divergences, with testable collider and gravitational wave signatures.

Findings

Predicts an extra scalar detectable at colliders

Induces a first-order dark/electroweak phase transition

Vacuum stability up to the Planck scale

Abstract

Assuming that naturalness should be modified by ignoring quadratic divergences, we propose a simple extension of the Standard Model where the weak scale is dynamically generated together with an automatically stable vector. Identifying it as thermal Dark Matter, the model has one free parameter. It predicts one extra scalar, detectable at colliders, which triggers a first-order dark/electroweak cosmological phase transition with production of gravitational waves. Vacuum stability holds up to the Planck scale.
