“…These calculations could be used to extract an experimental value of the nuclear anapole moment, which in turn could be used to study parity-violating nuclear forces. The accuracy of these calculations could be improved with the inclusion of higher-order correlation corrections, such as the double-core polarization [35], structure radiation [33], and ladder diagrams [53], as well as other small corrections such as the Breit [55] and QED [56] corrections.…”

We perform calculations of s-d 5/2 nuclear-spin-dependent parity nonconservation amplitudes for Rb, Cs, Ba + , Yb + , Fr, Ra + , and Ac 2+. These systems prove to be good candidates for use in atomic experiments to extract the so-called anapole moment, a P-odd T-even nuclear moment important for the study of parity-violating nuclear forces. We also extend our previous works by calculating the missed spin-dependent amplitudes for the s-d 3/2 transitions in the above systems.

“…At the moment, however, for certain systems there exists small, but significant, disagreement. A recent study of one particular many-body effect, the so-called double core polarisation, that may have been missed in some calculations suggests that this effect has the potential to resolve some of the disagreement in the literature [88].…”

Studying the violation of parity and time-reversal invariance in atomic systems has proven to be a very effective means for testing the electroweak theory at low energy and searching for physics beyond it. Recent developments in both atomic theory and experimental methods have led to the ability to make extremely precise theoretical calculations and experimental measurements of these effects. Such studies are complementary to direct high-energy searches, and can be performed for just a fraction of the cost. We review the recent progress in the field of parity and time-reversal violation in atoms, molecules, and nuclei, and examine the implications for physics beyond the Standard Model, with an emphasis on possible areas for development in the near future.

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.
