We perform a global analysis of searches for the permanent electric dipole moments (EDMs) of the neutron, neutral atoms, and molecules in terms of six leptonic, semileptonic, and nonleptonic interactions involving photons, electrons, pions, and nucleons. By translating the results into fundamental charge-conjugation-parity symmetry (CP) violating effective interactions through dimension six involving standard model particles, we obtain rough lower bounds on the scale of beyond the standard model CP-violating interactions ranging from 1.5 TeV for the electron EDM to 1300 TeV for the nuclear spin-independent electron-quark interaction. We show that planned future measurements involving systems or combinations of systems with complementary sensitivities to the low-energy parameters may extend the mass reach by an order of magnitude or more.

- Electric dipole moments of atoms, molecules, nuclei, and particles (2017, methodology): “The magnitude of ḡ (2) π is expected to be suppressed by a factor of 100 or more relative to ḡ (0) π and ḡ (1) π based on chiral symmetry considerations and is typically neglected in the computation of the nucleon EDMs (Chupp and Ramsey-Musolf, 2015).”
- Physics beyond colliders at CERN: beyond the Standard Model working group report (2019, background): “For almost all particles speculative models exist which can provide for EDMs almost as large as the present experimental limits [136].”
