Beyond freeze-in: Dark matter via inverse phase transition and gravitational wave signal
Original language description
We propose a novel scenario of dark matter production naturally connected with generation of gravitational waves. Dark matter is modeled as a real scalar, which interacts with the hot primordial plasma through a portal coupling to another scalar field. For a particular sign of the coupling, this system exhibits an inverse second order phase transition. The latter leads to an abundant dark matter production, even if the portal interaction is so weak that the freeze-in mechanism is inefficient. The model predicts domain wall formation in the Universe, a long time before the inverse phase transition. These domain walls have a tension decreasing with time and completely disappear at the inverse phase transition so that the problem of overclosing the Universe is avoided.
