Dark Matter Freeze-In with a Heavy Mediator: Beyond the EFT Approach
We study dark matter freeze-in scenarios where the mass of the mediator particle that couples dark matter to the Standard Model is larger than the reheat temperature, T$_{RH}$, in the early Universe. In such setups, the standard approach is to work with an effective field theory (EFT) where the medi...
