    • On the other hand, purely electroweak baryogenesis based on the sphaleron effects appears to be excluded for the case of the standard model without supersymmetry, and highly constrained as regards the available parameter space for the case of the supersymmetric standard model, owing to the LEP lower limit on the Higgs boson mass ≥ 115 GeV. For a recent review of these and other mechanisms and also for relevant references, see, e.g., M. Dine and A. Kusenko, hep-ph/0303065.
