Super-WIMP meets freeze-in — •Jan Heisig1 and Mathias Garny2 — 1Université catholique de Louvain — 2Technische Universität München
Non-thermalized dark matter is a cosmologically valid alternative to the paradigm of weakly interacting massive particles. For dark matter belonging to a Z2-odd sector that contains in addition a thermalized mediator particle, dark matter production proceeds in general via both the freeze- in and super-WIMP mechanism. We highlight their interplay and emphasize the connection to long-lived particles at colliders. For the explicit example of a colored t-channel mediator model we map out the entire accessible parameter space, cornered by bounds from the LHC, big bang nucleosynthesis and Lyman-alpha forest observations, respectively. We discuss prospects for the HL- and HE-LHC.
