Measurement of the Higgs-boson CP properties using decays into WW and ZZ at the Photon Collider

Higgs-boson production at the Photon Collider at TESLA is studied for masses from 180 to 350 GeV, using realistic luminosity spectra and detector simulation. Parity of the SM Higgs-boson can be verified from the measurement of the interference effects in the W+ W- decay channel and of the angular correlations in the decays of W+ W- and ZZ pairs. SM-like Two Higgs Doublet Model (2HDM II) and model with the generic higgs couplings are considered.
