摘要
We evaluate the fluxes of up-going muons detectable in a neutrino telescope and due to the annihilation of relic neutralinos in the Earth and in the Sun, taking realistically into account the fact that neutralinos might provide only a fraction of the local (solar neighbourhood) dark matter (DM). We determine the relation between the exposure At of the neutrino telescope (A being the telescope area, t the life time) and the explorable range of the neutralino mass and composition, when the signal-to-background ratio is optimized by an appropriate angular selection.
