Study of the CP-violating effects with gg → Η → τ+τ– process

Study of the gg → Η → τ + τ – process was performed at Monte Carlo level within the framework of searching for CP-violating effects. The sensitivity of chosen observables to CP-parity of the Higgs boson was demonstrated for hadronic 1-prong τ decays (τ ± → π ± , ρ ± ). Monte Carlo samples for the gg → Η → τ + τ - process were generated including the parton hadronisation to final state particles. This generation was performed for the Standard Model Higgs boson, the pseudoscalar Higgs boson, the Z → τ + τ – background, and mixed CP-states of the Higgs boson.
