Abstract: The scalar extensions of the Standard Model are widely predicted by a lot of new physics models. But till now, 125GeV Higgs boson is the only scalar we found. In this talk, I will explain why the CP-odd component in Higgs boson indicates extended scalars and focus on two cases: the CP mixture state case and the degenerate state case. Based on the Two-Higgs-Doublet Model, I will discuss the classification of the CP phase in this model in a geometric view and how can we find the degenerate CP-odd component from the Di-Higgs measurement.
