Description
Many Standard Model extensions feature a dark matter (DM) candidate produced via freeze-out, but often fail to account for the full relic density. We show that adding a second DM candidate via the freeze-in mechanism can resolve this issue. In such two-component DM models, the freeze-out particle may remain undetectable due to its low density, while a Feebly Interacting Massive Particle (FIMP) provides the missing contribution. A collider signal without direct or indirect detection could thus hint at a FIMP. The freeze-in DM, due to its small couplings, leaves the rest of the phenomenology unchanged.
