Fermion EDMs with Minimal Flavor Violation

Understand

We study the electric dipole moments (EDMs) of fermions in the standard model supplemented with right-handed neutrinos and its extension including neutrino seesaw mechanism under the framework of minimal flavor violation (MFV).

• In the quark sector, we find that the current experimental bound on the neutron EDM does not yield a significant restriction on the scale of MFV.
• In addition, we consider how MFV may affect the contribution of the strong theta-term to the neutron EDM.
• For the leptons, the existing EDM data also do not lead to strict limits if neutrinos are Dirac particles.
