- Abstract
- We study freeze-in scenarios in which the interactions of dark matter with the Standard Model are mediated by a heavy vector-like fermion with a mass that is higher than the reheating temperature of the Universe. In such scenarios freeze-in requires sizeable interactions between the two sectors which, in turn, implies that prompt LHC dark matter searches become relevant, unlike in conventional scenarios of freeze-in. We examine the interplay of long-lived and prompt searches and show that their role is highly complementary in constraining different regions of the parameter space.
