Abstract
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 TVPC mass scale ${\ensuremath{\Lambda}}_{\mathrm{TVPC}}$ of 150 TeV for new TVPC strong interactions. These results imply a value of ${10}^{\ensuremath{-}15}$ or smaller for the ratio of low-energy TVPC matrix elements to those of the residual strong interaction.
