Several well-motivated mechanisms for dark matter (DM) production in the early Universe can give rise to long-lived particle (LLP) signatures at high-energy collider experiments. A prime example is "Freeze-in" of very weakly coupled DM particles which never achieve thermal equilibrium with the Standard Model (SM). We examine the LLP signatures of DM through the decay of parent particles and explore the complementarity of ATLAS/CMS and other proposed detectors like MATHUSLA in probing such scenarios.
