G. B\'elanger, S. Chakraborti, A. Pukhov
TL;DR
This paper reviews feebly interacting particles (FIMPs) as dark matter candidates, discussing their production in the early universe and potential signatures in high-energy, high-intensity, astroparticle, and cosmological observations.
Contribution
It provides a comprehensive overview of FIMP dark matter scenarios, highlighting recent developments and experimental prospects.
Findings
FIMPs can account for dark matter without thermal equilibrium.
Various detection strategies are proposed for FIMPs in different experimental settings.
FIMP models have distinctive signatures in cosmology and high-energy experiments.
Abstract
We briefly review scenarios with feebly interacting particles (FIMPs) as dark matter candidates. The discussion covers issues with dark matter production in the early universe as well as signatures of FIMPs at the high energy and high intensity frontier as well as in astroparticle and cosmology.
