Dark matter going nuclear: light force mediators and bound states

Kalliopi Petrakis (Sorbonne University)


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.
