Supersymmetric Relics

After recalling the motivations for expecting supersymmetry to appear at energies 1 TeV, the reasons why the lightest supersymmetric particle is an ideal candidate for cold dark matter are reviewed. Recent calculations of the relic density including coannihilations and rapid annihilations through direct-channel Higgs boson poles are presented. The experimental constraints from LEP and elsewhere on supersymmetric dark matter are reviewed. The potential implications of a Higgs boson weighing about 115 GeV and the recent measurement of the anomalous magnetic moment of the muon are summarized.
