摘要：

Requiring that the baryon number of the universe be generated by anomalous electroweak interactions places strong constraints on the minimal supersymmetric standard model. In particular, the electric dipole moment of the neutron must be greater than 10(-27) e cm. Improvement of the current experimental bound on the neutron's electric dipole moment by one order of magnitude would constrain the lightest chargino to be lighter than 88 GeV, and the lightest neutralino to be lighter than 44 GeV. In extensions of this model with gauge singlet superfields all of these bounds are eliminated.
