Description

I review the concept of dark matter freeze-in at stronger coupling. It assumes that the Standard Model (SM) bath temperature has never been high, which allows for a significant coupling between dark matter and the SM, without thermalization. As a result, this class of freeze-in models can be probed via direct DM detection and at colliders. The framework also allows for observable warm dark matter with masses far below 1 MeV.
