我们研究了在分析双Higgs双重态模型时经常假定的三个特征的起源：(I)软破缺的Z2对称性，(Ii)CP不变的Higgs势和(Iii)简并的质量谱。我们扩展了电弱规范对称性，引入了额外的规范对称性和额外的标量，并证明了我们的模型在低能下有效地推导出了两希格斯双态模型，自然地保持了这三个特征。我们还发现，这些模型可以解决强CP问题。
We investigate origin of three features that are often assumed in analysis of two-Higgs doublet models:(i) softly broken Z 2 symmetry,(ii) CP invariant Higgs potential, and (iii) degenerated mass spectra. We extend electroweak gauge symmetry, introducing extra gauge symmetry and extra scalars, and we show that our models effectively derive two-Higgs doublet models at low energy which naturally hold the three features. We also find that the models can solve the strong CP problem.
