“…The Weinberg operator is chiral invariant and therefore its contribution toḡ 0,1 is suppressed by m 2 π /Λ 2 χ where Λ χ ∼ 1 GeV [58,68]. Nevertheless, power counting indicates that nuclear EDMs can still significantly depend onḡ 0,1 induced by the Weinberg operator [68,72], but explicit calculations show that the largest contributions arise from the constituent nucleon EDMs [73,74]. We will therefore neglectḡ 0,1 from the Weinberg operator.…”

Abstract:We investigate direct and indirect constraints on the complete set of anomalous CP-violating Higgs couplings to quarks and gluons originating from dimension-6 operators, by studying their signatures at the LHC and in electric dipole moments (EDMs). We show that existing uncertainties in hadronic and nuclear matrix elements have a significant impact on the interpretation of EDM experiments, and we quantify the improvements needed to fully exploit the power of EDM searches. Currently, the best bounds on the anomalous CP-violating Higgs interactions come from a combination of EDM measurements and the data from LHC Run 1. We argue that Higgs production cross section and branching ratios measurements at the LHC Run 2 will not improve the constraints significantly. On the other hand, the bounds on the couplings scale roughly linearly with EDM limits, so that future theoretical and experimental EDM developments can have a major impact in pinning down interactions of the Higgs.

“…In addition, the nuclear Schiff moments depend on the constituent nucleon EDMs. As far as we are aware, this has only been calculated for d Hg [74], with the result α n = 1.9(1) and α p = 0.20 (6). We neglect possible contributions from CPV short-range nucleon-nucleon interactions but stress that this assumption is untested.…”

We discuss in detail the search for a permanent electric dipole moment (EDM) of the 199 Hg atom reported by Griffith et al. [Phys. Rev. Lett. 102, 101601 (2009)]. The upper bound, d( 199 Hg) < 3.1 × 10 −29 e cm (95% C.L.), is a factor of 7 improvement over the best previous EDM limit for 199 Hg, provides the most sensitive probe to date for EDMs in diamagnetic atoms, and sets new limits on time-reversal symmetry violation in extensions to the standard model. This paper provides extensive discussion of the techniques used to search for the 199 Hg EDM and the implications of the new 199 Hg EDM limit for CP violation in elementary particle interactions.

Abstract. Existence of the electric dipole moment (EDM) is deeply related with time-reversal invariance. The EDM of a diamagnetic atom is mainly induced by the nuclear Schiff moment. After carrying out the shell model calculations to obtain wavefunctions for Xe isotopes, we evaluate nuclear Schiff moments for Xe isotopes to estimate their atomic EDMs. We estimate the contribution from each single particle orbital for the Schiff moment. It is found that the contribution on the Schiff moment is very different from orbital to orbital.
