Supersymmetric Dark Matter Detection at Post-LEP Benchmark Points [PDF]

, 2001
We review the prospects for discovering supersymmetric dark matter in a recently proposed set of post-LEP supersymmetric benchmark scenarios. We consider direct detection through spin-independent nuclear scattering, as well as indirect detection through ...
