Scientific paper

High-energy neutrinos could be emitted from the center of the Sun as annihilation products of heavy galactic dark-matter particles. We analyze neutrino events observed by the Kamiokande detector to search for such neutrinos. The observed upper limits on solar high-energy neutrinos from these data set limits on the mass and density of certain galactic dark matter. The particles analyzed are heavy Dirac neutrinos (νD), heavy Majorana neutrinos (νM), Higgsinos (h~), sneutrinos (ν~) with three flavors, and photinos (γ~) as the lightest supersymmetric particles. Excluded mass regions are obtained for each dark-matter candidate: 3 GeV
