We calculate for the first time the electric dipole moment (EDM) of the deuteron, 3 H, and 3 He nuclei generated by the one-meson exchange CP-odd nuclear force in the standard model. The effective |∆S| = 1 four-quark operators are matched to the |∆S| = 1 standard model processes involving the CP phase of the Cabibbo-KobayashiMaskawa matrix at the electroweak scale and run down to the hadronic scale µ = 1 GeV according to the renormalization group evolution in the next-to-leading logarithmic order. At the hadronic scale, the hadron matrix elements are modeled in the factorization approach. We then obtain the one-meson (pion, eta meson, and kaon) exchange CP-odd nuclear force, which is the combination of the |∆S| = 1 meson-baryon vertices which issue from the penguin operator and the hyperon-nucleon transition. From this CP-odd nuclear force, the nuclear EDM is calculated with the realistic Argonne v18 interaction and the CP-odd nuclear force using the Gaussian expansion method. It is found that the EDMs of light nuclear systems are of order O(10 −31 )e cm. We also estimate the standard model contribution to other hadronic CP violating observables such as the EDMs of 6 Li, 9 Be nuclei, and the atomic EDMs of 129 Xe, 199 Hg, 211 Rn, and 225 Ra generated through the nuclear Schiff moment. We then analyze the source of theoretical uncertainties and show some possible ways to overcome them.

Abstract:The constraint on the R-parity violating supersymmetric interactions is discussed in the light of current experimental data of the electric dipole moment of neutron, 129 Xe , 205 Tl, and 199 Hg atoms, and YbF and ThO molecules. To investigate the constraints without relying upon the assumption of the dominance of a particular combination of couplings over all the rest, an extensive use is made of the linear programming method in the scan of the parameter space. We give maximally possible values for the EDMs of the proton, deuteron, 3 He nucleus, 211 Rn, 225 Ra, 210 Fr, and the R-correlation of the neutron beta decay within the constraints from the current experimental data of the EDMs of neutron, 129 Xe, 205 Tl, and 199 Hg atoms, and YbF and ThO molecules using the linear programming method. It is found that the R-correlation of the neutron beta decay and hadronic EDMs are very useful observables to constrain definite regions of the parameter space of the R-parity violating supersymmetry.

“…At present, the most stringent upper limit on the EDM in diamagnetic atom is set by the 199 Hg experiment [1] as |d( 199 Hg)| < 0.31 × 10 −28 ecm. The EDM of a diamagnetic atom primarily arises from a CP-odd nuclear moment, the Schiff moment S [2], via P and T-odd nucleon-nucleon (NN) interactions [3]. Since the Schiff moment depends on the nuclear structure, the magnitude of EDM should be different for different nuclear species.…”

EDM measurement in 129Xe atom using dual active feedback nuclear spin maser

et al. 2014

View full text Add to dashboard Cite

The technique of an active nuclear spin maser is adopted in the search for electric dipole moment in a diamagnetic atom 129 Xe. In order to reduce systematic uncertainties arising from long-term drifts of the external magnetic field and from the contact interaction between longitudinal polarized Rb atoms and 129 Xe spin, a 3 He comagnetometer with a double-cell geometry was employed. The remaining shift, which turned out to show some correlation with the cell temperature, was mitigated by stabilizing the cell temperature. As a result, the frequency drift of the 129 Xe maser was reduced from 12 mHz to 700 μHz, and the determination precision of frequency of 8.7 nHz was obtained for a 2 × 10 4 s measurement time using the double-cell geometry cell.
