Abstract

We calculate the contribution of the |ΔS|=1K meson exchange process generated by the Cabibbo-Kobayashi-Maskawa matrix to the electric-dipole moment (EDM) of the Be9 nucleus by considering the αn-αΛ channel coupling. It is found that the effect of the Pauli exclusion principle is not important intermediate S=-1 state, and that the result is consistent with the EDM of Be9 calculated with the |ΔS|=1 interactions as a perturbation without considering the nucleus-hypernucleus mixing. Our result suggests that the effect of the |ΔS|=1 interactions is neither suppressed nor enhanced in nuclei, if the difference of binding energies between the nucleus and the hypernucleus is small compared with the hyperon-nucleon mass difference.
