Electric dipole moments, new forces and dark matter
New sources of CP violation beyond the Standard Model are crucial to explain the baryon asymmetry in the Universe. We discuss the impact of new CP violating interactions in theories where a dark matter candidate is predicted by the cancellation of gauge ...

Electric dipole moments in the MSSM reloaded [PDF]
We present a detailed study of the Thallium, neutron, Mercury and deuteron electric dipole moments (EDMs) in the CP-violating Minimal Supersymmetric extension of the Standard Model (MSSM). We take into account the complete set of one-loop graphs, the dominant Higgs-mediated two-loop diagrams, the complete CP-odd dimension-six Weinberg operator and the ...

THE ELECTRIC AND MAGNETIC DIPOLE MOMENTS OF THE NEUTRON* [PDF]
In 1950 Purcell and Ramsey pointed out that the parity arguments then used to prove that particles and nuclei could not have electric dipole moments, must be based on an experimental rather than a theoretical basis.

We have examined the anomalous electromagnetic moments of the tau lepton in the processes e−γ→νeτν¯τ (γ is the Compton backscattering photon) and e−e+→e−γ⁎e+→νeτν¯τe+ (γ⁎ is the Weizsacker–Williams photon) with unpolarized and polarized electron beams at

Electric dipole moment of a BPS monopole [PDF]
Monopole ``superpartner'' solutions are constructed by acting with finite, broken supersymmetry transformations on a bosonic N=2 BPS monopole. The terms beyond first order in this construction represent the backreaction of the the fermionic zero-mode state on the other fields.

Cesium nD_{J}+6S_{1/2} Rydberg molecules and their permanent electric dipole moments
Cs_{2} Rydberg-ground molecules consisting of a Rydberg, nD_{J} (33≤n≤39), and a ground-state atom, 6S_{1/2} (F=3 or 4), are investigated by photo-association spectroscopy in a cold atomic gas.

Electric dipole moments in split supersymmetry [PDF]
We perform a quantitative study of the neutron and electron electric dipole moments (EDM) in Supersymmetry, in the limit of heavy scalars. The leading contributions arise at two loops. We give the complete analytic result, including a new contribution associated with Z-Higgs exchange, which plays an important and often leading role in the neutron EDM ...

We briefly discuss the current status of lattice QCD simulations and review selective results on nucleon observables focusing on recent developments in the lattice QCD evaluation of the nucleon form factors and radii, parton distribution functions and ...

Electric dipole moments with and beyond flavor invariants
In this paper, the flavor structure of quark and lepton electric dipole moments in the SM and beyond is investigated using tools inspired from Minimal Flavor Violation.

Confronting Higgcision with electric dipole moments [PDF]
Current data on the signal strengths and angular spectrum of the 125.5 GeV Higgs boson still allow a CP-mixed state, namely, the pseudoscalar coupling to the top quark can be as sizable as the scalar coupling: $C_u^S \approx C_u^P =1/2$. CP violation can then arise and manifest in sizable electric dipole moments (EDMs).
