Description:
WIMP of FIMP dark matter?

Can dark matter properties be constrained if dark matter particles interact only feebly with the Standard Model fields? The answer is yes. By studying both cosmological and astrophysical constraints, we show that stringent constraints on dark matter properties can be derived even in case the dark matter sector is decoupled from the Standard Model sector and dark matter consists of FIMPs. By taking the Higgs portal model as a representative example, we study in detail scenarios where the hidden sector does not thermalize with the Standard Model sector and, among other things, derive a lower bound on dark matter self-interaction strength.
