Abstract: The supersymmetric standard model (SSM) contains a new source of CP violation in the mass-squared matrices for squarks, which could imply the t squark mediation of the charge transport mechanism producing the baryon asymmetry of the universe. This CP-violating source also induces the electric dipole moment (EDM) of the neutron. We show that this t-squark transport can lead to a baryon asymmetry consistent with its observed value within reasonable ranges of SSM parameters, where the neutron EDM has a magnitude slightly smaller than its experimental upper bound.
