# Gravitational wave, collider and dark matter signals from a scalar singlet electroweak baryogenesis

## TL;DR

This paper explores a minimal extension of the Standard Model with a scalar singlet, examining its potential signals in gravitational waves, colliders, and dark matter detection for electroweak baryogenesis.

## Contribution

It demonstrates that gravitational wave observations can detect signals from this model even when collider searches cannot.

## Key findings

- Significant parameter space where gravitational waves are detectable.
- Collider searches may not observe signals in some regions.
- Dark matter detection signals are also analyzed.

## Abstract

We analyse a simple extension of the SM with just an additional scalar singlet coupled to the Higgs boson. We discuss the possible probes for electroweak baryogenesis in this model including collider searches, gravitational wave and direct dark matter detection signals. We show that a large portion of the model parameter space exists where the observation of gravitational waves would allow detection while the indirect collider searches would not.
