Supersymmetric Dark Matter: Relic Density and Detection
  The Lightest Supersymmetric Particle (LSP) makes a good Dark Matter (DM) candidate, since its relic density quite naturally comes out close to the cosmologically required value. This is true even in minimal Supergravity models with radiative symmetry breaking, which have a rather small number of free parameters. On the other hand, the experimental detection of SUSY DM might be quite difficult, necessitating km$^2$ size neutrino detectors or direct detection experiments with several tons of detector material.
