We consider the implications of experimental limits on the permanent electric dipole moment (EDM) of the electron and neutron for possible new time-reversal violating (TV) parity-conserving (PC) interactions. We show that the constraints derived from one-loop contributions to the EDM exceed previously reported two-loop limits by more than an order of magnitude and imply a lower bound on the new...

The question of CP violating phases in supersymmetry and electric dipole moments (EDMs) is considered within the framework of supergravity grand unification (GUT) models with a light (< ∼1 TeV) mass spectrum. In the minimal model, the nearness of the t-quark Landau pole automatically suppresses the t-quark cubic soft breaking phase at the electroweak scale. However, current EDM data require the...

Electric Dipole Moments and the Mass Scale of New T-Violating, P-Conserving Interactions

We consider the implications of experimental limits on the permanent electric dipole moment (EDM) of the electron and neutron for possible new timereversal violating (TV) parity-conserving (PC) interactions. We show that the constraints derived from one-loop contributions to the EDM exceed previously reported two-loop limits by more than an order of magnitude and imply a lower bound on the new ...
