Local Operators

We utilize the gradient flow to define and calculate electric dipole moments induced by the strong QCD θ-term and the dimension-6 Weinberg operator. The gradient flow is a promising tool to simplify the renormalization pattern of local operators. The results of the nucleon electric dipole moments are calculated on PACS-CS gauge fields (available from the ILDG) using Nf = 2+1, of discrete size 323×64 and spacing a ≃ 0.09 fm. These gauge fields use a renormalization-group improved gauge action and a nonperturbatively O(a) improved clover quark action at β = 1.90, with cSW = 1.715. The calculation is performed at pion masses of mπ ≃ 411, 701 MeV.

Generic Class

We dicuss the utility of precision probes for flavour-diagonal CP-violation, namely, searches for electric dipole moments of nucleons, atoms, and molecules, in looking for new physics thresholds that manifest themselves primarily through higher dimensional operators. After reviewing the status of the electric dipole moment (EDM) constraints, we consider first the sensitivity to a generic class of dimension-five operators generated at a supersymmetric threshold, through their contribution to CP- and flavour-violating observables. Such thresholds can be probed by EDMs up to a scale of order 108 GeV depending on the flavour structure. We then turn to consider the possibility that electroweak baryogenesis is made feasible by the introduction of dimension-six operators at a TeV-scale threshold. The EDM costraints on dimension-six couplings of the Higgs to the fermions currently still allow a reasonable window in parameter space for these models, but the next generation of experiments should provide a conclusive test.

Supersymmetric Theories

We review the present status of the CP violating problem in supersymmetric extensions of the standard model. We analyze the constraints imposed by the experimental limits of the electron, neutron, and mercury electric dipole moments on the supersymmetric CP phases and show that only the scenarios with flavour-off-diagonal CP violation remain attractive. These scenarios require Hermitian Yukawa matrices which naturally arise in models with left–right symmetry or a SU(3) flavour symmetry. In this case, εK and ε′/ε can be saturated by a small non-universality of the soft scalar masses through the gluino and chargino contributions respectively. The model also predicts a strong correlation between A CP (b → sγ) and the neutron electric dipole moment. In this framework, the standard model gives a the leading contribution to the CP asymmetry in B → ψKS decay, while the dominant chargino contribution to this asymmetry is < 0.2. Thus, no constraint is set on the non-universality of this model by the recent BaBar and Belle measurements.

The high-field first and second order Zeeman effect has been observed in Ethyleneoxidein order to determine the sign of the electric dipole moments from the g-values of different isotopes. The experimental data indicate that in Ethyleneoxide the negative end is at the Oxygen while in Pyridine the result is not conclusive. The effect of vibrations is discussed in some detail and it is concluded that the vibrational dependance of the g-values should be accounted for if the sign of the dipole moment is determined from Zeeman data (at least if H ↔ D substitutions are involved).

AbstractThe experimental electric dipole moments in dioxane solution, together with the calculated dipole moments for some selected conformers, are reported for the two natural prostaglandins F1α and F1β. The results obtained are compatible with a hypothesized hairpin structure for these molecules in solution.

Electric dipole moments and molar Kerr constants are reported for ammonia, trimethylamine, trimethylamine oxide, 1,4- diazabicyclo[2,2,2]octane and its monohydrate in non-polar solvents. The dipole moment now found for 1,4-diazabicyclo[2,2,2]octane differs substantially from previously recorded values. Effective polarizability anisotropies are derived for each of the anhydrous molecules and for the N-H and N-C bonds. The effect of solute interactions with benzene is explored.

Scaling Dimension

We study the charged lepton electric dipole moment which is induced by the scalar unparticle mediation and we predict the appropriate range for the free parameters appearing in the effective Lagrangian which drives the unparticle-standard model lepton interactions. We observe that the charged lepton electric dipole moment is strongly sensitive to the scaling dimension du of the unparticle and the new couplings in the effective interaction. Furthermore, we see that the current experimental limits of charged lepton electric dipole moments can ensure an appropriate range for these free parameters.
