High-energy neutrino fluxes from supermassive dark matter
Abstract
We calculate the fluxes and energy spectra of high-energy (E > 50 GeV) neutrinos from the annihilations of supermassive (108 GeV < M < 1016 GeV), strongly interacting dark matter particles in the core of the Sun. We take all significant aspects of neutrino propagation through matter into account, as well as oscillations in matter and vacuum. We also calculate the resulting event rates in an idealized 1 km3 ice detector. We find that the signal should be well above background and easily observed by next-generation neutrino detectors such as IceCube.
