Single-step first order phase transition and gravitational waves in a SIMP dark matter scenario
We investigate the non-zero temperature dynamics of a sub-GeV dark matter scenario freezing-out via self-interactions. As a prototype, we take up the case of a scalar dark matter species undergoing 3→2 number changing annihilations catalysed by another scalar. We study the shape of the thermal poten...
