dc.descriptionI rebuild a conventional two-Higgs doublet model by relaxing the spontaneous CP violation and considering approximate global U(1) family symmetries. So that the domain-wall problem does not explicitly arise at the weak scale, but CP violation still solely originates from a single CP-phase in the vacuum after spontaneous symmetry breaking. With this phase four types of CP-violating mechanism are induced in the model. In particular, by a new type of the mechanism, both the indirect- and direct- CP violation (i.e. $ε$ and $ε'/ε$) in kaon decay and the neutron electric dipole moment can be consistently accommodated. The masses of the exotic scalars are weakly constrained in the model and searching for these particles is worthwhile in the presently accessible energy range. Substantial CP violation may occur in the heavy quark and lepton sectors and probing their effects provides a challenge at B-factory and colliders.
