摘要：

We propose a model of softly or spontaneously broken CP symmetry in which the CP-violating mechanism originates from the charged Higgs sector naturally. The mechanism not only accounts for the measured value of the CP-violating parameter epsilon but also accommodates the current limits on epsilon'/epsilon. The model naturally prevents tree-level flavor changing neutral currents and the strong. CP problem. Electric dipole moments vanish to one (or more) loops. Surprisingly similar to the Kobayashi-Maskawa model, our model is of milliweak character but with seemingly superweak phenomenology.
