Dark matter freeze-in with a heavy mediator: beyond the EFT approach
Abstract 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 th...
