Description

If the SM-like Higgs boson is realized as a mixture of scalar and pseudoscalar states, the CP violating mixing angle can be measured through various Higgs boson production and decay channels. Here we consider Higgs to +- decays, at 240 GeV CEPC with 5.6 ab-1 of simulated data. Preliminary projections of the absolute uncertainty of the mixing angle are given, for the Higgs boson production in Higgsstrahlung, where the primary Z0 boson decays inclusively.
