Abstract
Effects of CP and T invariance violation are studied in the most general interaction of the Higgs boson with the intermediate vector W ± and Z bosons. Various angular distributions of the cascade decay Φ → W + W −/ZZ → 4 of fermions in the transversity and helicity systems are calculated, and asymmetries are constructed and evaluated. It is shown that studying the azimuthal angle distribution of the process Φ → ZZ → (e − e +)(μ−μ+) in the transversity system is effective for measuring the spatial parity of the Higgs boson.
