Resumen

We investigate rare decays of Higgs via exchange of two almost degenerate heavy on-shell Majorana neutrinos Nj (j = 1, 2): Γ± = Γ(h → νkNj→ νk±π), and into the open quark channels Γ± = Γ(h → νkNj→ νk±UD), where UD are two jets of open quarks (U¯ D, or UD¯ , where U = u, c and D = d, s). The related CP violation asymmetry ACP = (Γ− Γ+)/(Γ + Γ+) is studied in detail. We take into account the N1-N2 overlap and oscillation effects. We can see that for certain, presently acceptable, range of input parameters, such decays with open quark channels, and their asymmetries, could be detected in the International Linear Collider (ILC).
