摘要：

We present a minimal extension of the standard model (SM) where a Kobayashi-Maskawa (KM) phase is generated from spontaneous CP breaking at a high energy scale. The only additional fields are a charge - 1 3 vector-like quark and a singlet scalar S. In the limit V= 2|〈S〉|→∞, this model reduces to the SM with KM mechanism. For V as high as 10 -102 TeV, the neutron electric dipole moment lies in the range 10-26-10-28 e cm. © 1990.
