Dark Matter and Matter-Antimatter Asymmetry of the Universe from Gravitational Waves

I will present how gravitational wave detectors can be used to probe theories simultaneously explaining dark matter and the matter-antimatter asymmetry of the Universe. In particular, I will focus on an asymmetric dark matter model extending the Standard Model gauge symmetry by a non-Abelian gauge group, under which the leptons form doublets with new fermionic partners. One of those new fermions is a good dark matter candidate. The particle content of the model causes the effective potential to develop a new vacuum, which leads to a strong first order phase transition. This results in the production of gravitational waves via sound waves and bubble collisions. As our calculations show, the signatures of the model can be probed in upcoming gravitational wave experiments, including Cosmic Explorer, DECIGO, Big Bang Observer, and Einstein Telescope.
