Model-independent analysis of CP violation effects in decays of the Higgs boson into a Pair of the W and Z bosons

摘要

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 I broken vertical bar -> 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 I broken vertical bar -> ZZ -> (e (-) e (+))(mu(-)mu(+)) in the transversity system is effective for measuring the spatial parity of the Higgs boson.
