N2 - In the MSSM, LSP dark matter could arise from the decay of B-balls rather than from thermal relies, with a quite different dependence on the MSSM parameters and a natural correlation with the baryon asymmetry. We discuss the constraints imposed on the properties of B-balls and the MSSM spectrum by experimental constraints and show that B-balls cannot form from an Affleck-Dine condensate with 100% efficiency in the absence of LSP annihilations after they decay. For likely formation efficiencies the LSP and slepton masses are typically constrained to be light.
