Dark Matter Annihilation to Neutrinos: An Updated, Consistent & Compelling Compendium of Constraints

We place updated constraints on dark matter annihilation into neutrinos, using the most recently available data from neutrino detectors. We consider Galactic and extragalactic signals of s, p, and d-wave annihilation processes directly into neutrino pairs, and furthermore provide projections for next-generation neutrino experiments. Our constraints span dark matter masses from MeV to ZeV, ranging from ⟨σv⟩∼5×10−26 cm3s−1 to 10−19 cm3s−1, respectively. When directional information is available, constraints are strongest. Experiments that report directional and energy information of their events provide much stronger constraints, outlining the importance of making such data public.
