“…The concept of probing the QCD θ-term and BSM physics using EDMs of light nuclei has attracted much attention in recent years [8][9][10][11][12][13][14][15][16][17][18][19][20] and is the basic idea underlying plans for EDM measurements in dedicated storage rings [21][22][23][24][25]. The main advantage of light nuclei is that the associated nuclear physics is theoretically well under control, such that these systems can be used to probe the underlying CP-violating mechanism.…”

We provide a consistent and complete calculation of the electric dipole moments of the deuteron, helion, and triton in the framework of chiral effective field theory. The CP-conserving and CP-violating interactions are treated on equal footing and we consider CP-violating one-, two-, and three-nucleon operators up to next-to-leading-order in the chiral power counting. In particular, we calculate for the first time EDM contributions induced by the CP-violating three-pion operator. We find that effects of CP-violating nucleon-nucleon contact interactions are larger than those found in previous studies based on phenomenological models for the CP-conserving nucleon-nucleon interactions. Our results which apply to any model of CP violation in the hadronic sector can be used to test various scenarios of CP violation. As examples, we study the implications of our results on the QCD θ-term and the minimal left-right symmetric model.

“…The EDM is measurable in many systems, and many experimental measurements were done so far, including the neutron [17], atoms [18][19][20][21][22], molecules [23,24], etc. Recently, new technology using storage rings is making it possible to measure the EDM of charged particles [25][26][27][28][29][30][31][32][33]. The experimental measurement of the nuclear EDM is also developed, and is expected to be realized in the near future.…”

We calculate for the first time the electric dipole moment (EDM) of 13 C generated by the isovector CP-odd pion exchange nuclear force in the α-cluster model, which describes well the structures of low lying states of the 13 C nucleus. The linear dependence of the EDM of 13 C on the neutron EDM and the isovector CP-odd nuclear coupling is found to be d13 C = −0.33dn − 0.0020Ḡ(1) π . The linear enhancement factor of the CP-odd nuclear coupling is smaller than that of the deuteron, due to the difference of the structure between the 1/2 − 1 state and the opposite parity (1/2 + ) states. We clarify the role of the structure played in the enhancement of the EDM. This result provides good guiding principles to search for other nuclei with large enhancement factor. We also mention the role of the EDM of 13 C in determining the new physics beyond the standard model.

“…It should be noted that because of its rather small magnetic anomaly the deuteron is a particularly interesting candidate for a ring EDM experiment and a proposal with a sensitivity of 10 −27 e cm exists [ 39]. In this case scattering off a target will be used to observe a spin precession.…”

In nuclear physics numerous possibilities exist to investigate fundamental symmetries and interactions. In particular, the precise measurements of properties of fundamental fermions, searches for new interactions in β-decays, and violations of discrete symmeties offer possibilities to search for physics beyond standard theory. Precise measurements of fundamental constants can be carried out. Low energy experiments allow to probe New Physics at mass scales far beyond the reach of present accelerators or such planned for the future and at which predicted new particles could be produced directly.
