CP violation in the rare Higgs decays via exchange of on-shell almost degenerate Majorana neutrinos, H→ vkNj→ vkℓ −UD¯ and H→ vkNj→ vkℓ +U¯ D

We investigate rare decays of Higgs via exchange of two almost degenerate heavy on-shell Majorana neutrinos N-j (j = 1, 2): Gamma(+/-) = Gamma(h -> nu N-k(j)-> nu(k)l(+/-)pi(-/+)), and into the open quark channels Gamma(+/-) = Gamma(h -> nu N-k(j)-> nu(k)
