If the Universe contains a nearly critical density of photinos which are also assumed to constitute the dark matter in our galactic halo, then gravitational trapping by the Sun and ensuing annihilation in the solar core yields a significant flux of 250-MeV neutrinos. This results in about 2 neutrino-induced events per kiloton-year in an underground proton-decay detector.
Silk et al. (Mon,) studied this question.
