Dark Matter and Baryogenesis from Gravitational Waves

Gravitational wave detectors will be expressed to probe models of assymetric dark matter. Such theories can simultaneously explain dark matter and the matter-antimatter asymmetry of the Universe. I will present the results of our calculation for a model extending the Standard Model symmetry by a non-Abelian gauge group. Under this new symmetry, the leptons form doublets with new fermionic partners, one of which is a dark matter candidate. The model exhibits a strong first order phase transition at a high scale, which leads to the production of gravitational waves through sound waves and bubble collisions. The resulting signatures are within the reach of near-future gravitational wave experiments, like the Einstein Telescope, Cosmic Explorer, DECIGO, and Big Bang Observer.
