Description

We study freeze-in production of dark matter (DM) at temperatures far below the dark matter mass. The temperature of the Standard Model (SM) thermal bath may have never been high such that dark matter production via thermal emission has been Boltzmann suppressed. This allows for a significant coupling between the SM and DM, which is being probed by the direct DM detection experiments and invisible Higgs decay searches at the LHC.
