Revisiting theoretical analysis of the electric dipole moment of 129Xe

NUCLEAR MOMENTS 129Xe; analyzed available data; deduced contributions from the parity and time-reversal violating pseudoscalar-scalar (Ps-S) and scalar-pseudoscalar (S-Ps) electron-nucleus interactions along with electric dipole moments (EDMs) of electrons (de) interacting with internal electric and magnetic fields.

Effect of the Pauli exclusion principle in the electric dipole moment of 9Be with nullDsnull= 1 interactions

NUCLEAR STRUCTURE 9Be; calculated electric dipole moment (EDM) with the inclusion of ΔS=1 K-meson exchange processes generated by the Cabibbo-Kobayashi-Maskawa matrix by considering αn-αΛ channel coupling; deduced that effect of Pauli exclusion principle is not important for intermediate ΔS=-1 state, and that the result is consistent with the EDM of 9Be calculated as a perturbation without considering the nucleus-hypernucleus mixing.

Nuclear electric dipole moment in the cluster model with a triton: 7Li and 11B

NUCLEAR STRUCTURE 7Li, 11B; calculated electric dipole moments (EDM) in the cluster model with α and triton clusters as degrees of freedom, deduced sensitivity to CP violation in terms of the chiral effective-field theory. Calculations based on treatment of 7Li and 11B nuclei in the two- and three-body problem, respectively, and used the Gaussian expansion method with the assumption of one-meson exchange P, CP-odd nuclear forces. 6,7Li, 9Be, 11B, 13C; deduced that EDMs of the ground states of 6,7Li, 9Be, 11B and the first 1/2+ state of 13C obey an approximate counting rule accounting for the EDM of the cluster and the α-N polarization. Discussed role in probing new physics beyond the standard model.
