Description

If dark matter couples to force mediators that are much lighter than itself, then its interactions manifest as long-ranged. This gives rise to non-perturbative effects, including the existence of bound states. The formation of stable or metastable dark matter bound states can affect the dark matter phenomenology very significantly, including the dark matter relic density, indirect and direct detection signals, as well as the dark-matter self-scattering inside galaxies. I will give an overview of the effect of bound states on the dark matter production in the early universe, and discuss the connection to unitarity.
