The latest data from the ACME Collaboration have put a stringent constrainton the electric dipole moment d_e of the electron. Nevertheless, the standardmodel (SM) prediction for d_e is many orders of magnitude below the new result,making this observable a powerful probe for physics beyond the SM. We carry outa model-independent study of d_e in the SM with right handed neutrinos and itsextension with the neutrino seesaw mechanism under the framework of minimalflavor violation. We find that d_e crucially depends on whether neutrinos areDirac or Majorana particles. In the Majorana case, d_e can reach itsexperimental bound, and it constrains the scale of minimal flavor violation tobe above a few hundred GeV or more. We also explore extra CP-violating sourcesin the Yukawa couplings of the right-handed neutrinos. Such new sources canhave important effects on d_e.
