Seminarium "High Energy, Cosmology and Astro-particle Physics (HECA)"

The simplest dark matter models are those in which dark matter candidates annihilate via s-wave interactions during the thermal equilibrium process in the early universe. However, particle collider experiments and direct detection experiments have yet to yield decisive results. For dark matter candidates with masses ranging from MeV to 10 TeV, satisfying the conditions of early universe thermal equilibrium requires annihilation processes with velocity dependencies. In this talk, I will explore how indirect detection methods and cosmological observations can be used to search for such non-s-wave annihilating dark matter candidates.
