Description
The recent adoption of the LISA mission by the European Space Agency marks a significant milestone for gravitational wave cosmology, offering unprecedented sensitivity to gravitational wave backgrounds emitted at temperatures around a few hundred GeV. Intriguingly, this temperature range not only corresponds to the electroweak epoch but also coincides with the scale at which the freeze-out of WIMP dark matter is expected to happen. In this talk, I will present our recent work demonstrating how dark matter freeze-out triggered by a strong first-order phase transition in a dark sector can produce gravitational waves in the milli-Hertz range. Our findings suggest that a gravitational wave background detected by LISA could indicate such a phase transition, pointing to a specific dark matter candidate and opening new avenues for exploring the connection between Higgs physics, dark matter and gravitational waves.
