The Standard Model of particle physics (SM)gives an excellent description what is measured in particle collider experiments, but is less successful when applied to cosmology. In particular, the SM is unable to explain the existence of dark matter and the excess of baryons relative to anti-baryons. Both of these problems can be overcome by extending the SM to include supersymmetry. In the minimal
supersymmetric extension of the SM, the MSSM, the lightest
superpartner is stable, and therefore provides a dark matter
candidate. The cosmic baryon asymmetry can also be generated within the MSSM by the mechanism of electroweak baryogenesis. In this talk I will discuss the constraints placed on the MSSM by the requirement that it explain both the dark matter and the baryon asymmetry, as well as the experimental signatures that follow from these constraints.
