# Gravitational waves from the asymmetric-dark-matter generating phase transition

## TL;DR

This paper explores how a first order phase transition in a generative sector could produce gravitational waves, dark matter asymmetry, and other detectable signals, offering a multi-faceted approach to probing dark matter origins.

## Contribution

It introduces a model linking dark matter asymmetry generation with gravitational wave signals from phase transitions, highlighting detectable parameter space for future experiments.

## Key findings

- Strong phase transition regions can produce observable gravitational waves.
- Multiple signals including collider signatures and direct detection are predicted.
- Parameter space for detectable signals is identified.

## Abstract

The baryon asymmetry, together with a dark matter asymmetry, may be produced during a first order phase transition in a generative sector. We study the possibility of a gravitational wave signal in a model realising such a scenario. We identify areas of parameter space with strong phase transitions which can be probed by future, space based, gravitational wave detectors. Other signals of this scenario include collider signatures of a $Z'$, DM self interactions, a contribution to $\Delta N_{\rm eff}$ and nuclear recoils at direct detection experiments.
