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
