Description
We study in detail simple extension of the freeze-in mechanism based on kinematically forbidden production of dark matter through plasma effects. Focusing on Higgs portal model, where the dark matter is produced via forbidden decays of a scalar coupled to the Higgs, current and future collider, cosmological, and astrophysical probes are considered.
