A. Ilakovac et al., CP VIOLATION INDUCED BY HEAVY MAJORANA NEUTRINOS IN THE DECAYS OF HIGGS SCALARS INTO TOP-QUARK, W-BOSON AND Z-BOSON PAIRS, Physics letters. Section B, 317(4), 1993, pp. 609-616
We analyze the possibility of CP violation induced by heavy Majorana n
eutrinos in the decays of the Higgs particle into top-quark, W- and Z-
boson pairs. In the framework of various ''see-saw'' models with inter
family mixings, we find that Majorana neutrinos may give rise to sizab
le CP-odd observables at the one-loop electroweak order. Numerical est
imates of these CP-violating effects that may be detected in high-ener
gy colliders are presented.
