Two of the cosmological attractions of Supersymmetry are that it can provide an interesting relic density of Cold Dark Matter, and that it may be possible to generate the baryon asymmetry at the electroweak phase transition. I will show that there is a (small) area of parameter space in the Constrained MSSM that is consistent with experiment, where a baryon asymmetry produced at the phase transition could survive, and where the relic dark matter density contributes 0.1 < W_DM h² < 0.3.
