“…It is interesting , since it is also an important probe of the Weinberg operator [55]. In this work, we however do not consider it since its effect suffers from large theoretical uncertainty in the nuclear level calculation [58,59].…”

Electric dipole moment of C13

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.

“…Due to those advantages, theoretical evaluations of the nuclear EDM have been extensively done so far [45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60][61][62][63][64]. The EDM of nuclei was first estimated in the simple core+valence model, and an enhancement of the CP violation was suggested [42][43][44].…”

Abstract. The study of the couplings of the Higgs boson and of the top quark plays a preeminent role at the LHC, and could unveil the first signs of new physics. I will discuss the interplay of direct and indirect probes of certain classes of top and Higgs couplings. Including constraints from collider observables, precision electroweak tests, flavor physics, and electric dipole moments (EDMs), I will show that indirect probes are competitive, if not dominant, for both the CP-even and CP-odd top and Higgs couplings we considered. I will discuss the role of theoretical uncertainties, associated with hadronic and nuclear matrix elements, and indicate targets to further improve the constraining power of EDM experiments.

“…These EDMs can be calculated by first performing the nonperturbative matching to an extension of chiral perturbation theory that incorporates CPV hadronic interactions [25,26]. The EDMs of the nucleons, d n and d p , can then be expressed in terms of these CPV hadronic interactions, while for nuclear systems, such as 199 Hg, nuclear-structure calculations are required to do so.…”

We study the five chirality-flipping interactions that appear in the top-Higgs sector at leading order in the standard model effective field theory. We consider constraints from collider observables, flavor physics, and electric-dipole-moment experiments. This analysis results in very competitive constraints from indirect observables when one considers a single coupling at a time. In addition, we discuss how these limits are affected in scenarios in which multiple top-Higgs interactions are generated at the scale of new physics.9th International Workshop on the CKM Unitarity Triangle
