Dark Matter Freeze-In with a Heavy Mediator: Beyond the EFT Approach / Frangipane, Evan (UC, Santa Cruz) ; Gori, Stefania (UC, Santa Cruz) ; Shakya, Bibhushan (DESY ; CERN)
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, TRH, in the early Universe. [...]
