In the SM the Higgs boson is a scalar (CP-even) particle. Currently the 125 GeV Higgs boson is consistent with such a characterization. However, experimentally it is still possible to have some CP-admixture leading to CP violation in the Higgs sector. In this talk, we will see how from first principles one can make connections among the various CP violation possibilities, and how the observables have an underlying connection. Taking a specific example of Higgs-tau-tau Yukawa interaction, I will highlight these aspects, and show an interesting new possibility of utilizing Dalitz plot distribution to probe CP violation. This complementary methodology can play an important role in future explorations of CP violation in Higgs sector.
