Scientific paper

The neutralino, the lightest superpartner in many supersymmetric theories, is arguably the leading dark-matter candidate from both the cosmological and particle-physics points of view. Its mass is bracketed by a minimum value of tens of GeV, determined from unsuccessful accelerator searches, and a maximum value of several TeV, above which neutralinos ``overclose'' the Universe. If neutralinos exist in our galactic halo, they will be gravitationally captured by scattering off elements in the Sun. Annihilation of neutralinos in the Sun will produce a neutrino flux which can be detected on Earth and thus provide indirect evidence for galactic dark matter. We show that a 1-km2 area is the natural scale of a neutrino telescope capable of probing the GeV-TeV neutralino mass range by searching for high-energy neutrinos produced by their annihilation in the Sun.
