CP violation induced by heavy Majorana neutrinos in the decays of Higgs scalars into top-quark, W - and Z-boson pairs

We analyze the possibility of CP violation induced by heavy Majorana neutrinos in the decays of the Higgs particle into top-quark, W- and Z-boson pairs, in the framework of various ''see-saw'' models with interfamily mixings, we find that Majorana neutrinos may give rise to sizable CP-odd observables at the one-loop electroweak order. Numerical estimates of these CP-violating effects that may be detected in high-energy colliders are presented.
