Abstract
Astrophysical and cosmological evidence suggests that 85% of the mass in the Universe is not visible. This dark matter has yet to be incorporated into the standard model of particle physics. A leading candidate for dark matter is the weakly interacting massive particle. The production of weakly interacting dark matter in the early Universe implies possible ongoing self-annihilation to the standard model particles wherever dark matter exists today. This article provides a review of probes for the annihilation of dark matter into neutrinos over many orders of magnitude of dark matter mass. It reviews the experimental techniques that are used to detect neutrinos, places updated constraints on the dark matter self-annihilation cross section to neutrinos using recently available data, and forecasts the sensitivity of upcoming neutrino experiments.
