Experimental Bound

The neutron electric dipole moment (EDM) is investigated in detail. We assume a phenomenologically successful seesaw-type quark mass matrix. If the neutron EDM is observed at slightly below the present experimental bound (10–26–10–25 e · cm ), we can conclude that there must exist a vector-like quark a little heavier than the heavier neutral Higgs boson, or both of them have equal masses around 1 TeV.

Doublet Model

The Weinberg three-Higgs-doublet model of CP violation and its phenomenological implications are reviewed. CP violation which arises solely from charged-Higgs-boson exchange can be accommodated in the kaon system, but it is not compatible with the constraints inferred from the neutron electric dipole moment dn and from B physics. Therefore, charged-Higgs-boson exchange cannot be the dominant source of CP violation observed in KL decays. Limits on CP violation mediated by neutral-Higgs-boson exchange are derived from the dn induced by the mechanism of Barr and Zee.
