The Minimal Supersymmetric Standard Model has a candidate dark matter particle in its spectrum, and may be able to generate the baryon asymmetry of the Universe (BAU) at the electroweak phase transition. In the Constrained MSSM, we find the area of parameter space which is allowed by accelerator and precision tests, which produces a relic dark matter abundance in the observationally favored window 0.1 ≲ Ωh2 ≲ 0.3, and where baryon plus lepton number violating processes are out of equilibrium after the electroweak phase transition.
