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

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 $Z^{\prime }$, DM self interactions, a contribution to $\Delta N_{\mathrm{eff}}$ and nuclear recoils at direct detection experiments.
