Mass limits for dark-matter particles derived from high-energy neutrinos from the Sun

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 ({nu}{sub {ital D}}), heavy Majorana neutrinos ({nu}{sub {ital M}}), Higgsinos ({ital {tilde h}}), neutrinos ({tilde {nu}}) with three flavors, and photinos ({tilde {gamma}}) as the lightest supersymmetric particles. Excluded mass regions are obtained for each dark-matter candidate: 3 GeV{lt}{ital m}{sub {nu}{ital D}}{lt}100 GeV, 3 GeV{lt}{ital m}{sub n{tilde u}}{ital e}{lt}90 GeV, 3 GeV{lt}{ital m}{sub n}{tilde u}{mu}{lt}90 GeV, and 4 GeV{lt}{ital m}{sub n}{tilde u}{tau}{lt}90 GeV. No limits are obtained on the masses of {nu}{sub {ital M}}, {ital {tilde h}}, and {tilde {gamma}} yet.
