Abstract
A minimal model of spontaneous CP violation based on two-Higgs-doublet and two-Higgs-singlet fields is constructed. The model has a Peccei-Quinn-type U(1) symmetry which breaks at – GeV energy scale. Physical CP violation arises from scalar-pseudoscalar mixings. A relatively large electric dipole moment for charged leptons and small ‖ε’/ε‖ are predicted.
