Electric Dipole Moments and Polarizability in the Quark-Diquark Model of the Neutron

, 2010
For a bound state internal wave function respecting parity symmetry, it can be rigorously argued that the mean electric dipole moment must be strictly zero.

Naturalness Bounds on Dipole Moments from New Physics [PDF]

, 2001
Assuming naturalness that the quantum corrections to the mass should not exceed the order of the observed mass, we derive and apply model-independent bounds on the anomalous magnetic moments and electric dipole moments of leptons and quarks due to new ...

Electric Dipole Moment Enhancement Factor of Thallium

Physical Review Letters, 2012
The goal of this work is to resolve the present controversy in the value of the EDM enhancement factor of Tl. We have carried out several calculations by different high-precision methods, studied previously omitted corrections, as well as tested our methodology on other parity conserving quantities.

Constraining the dipole moments of the top quark

, 2011
We investigate the direct and indirect bounds on dipole operators involving the top quark. A careful analysis shows that the experimental upper limit on the neutron electric dipole moment strongly constrains the chromo-electric dipole of the top.

Electric Dipole Moments of Dyon and `Electron'

, 2008
The electric and magnetic dipole moments of dyon fermions are calculated within N=2 supersymmetric Yang-Mills theory including the theta-term. It is found, in particular, that the gyroelectric ratio deviates from the canonical value of 2 for the monopole

Toward verification of electroweak baryogenesis by electric dipole moments

Physics Letters B, 2016
We study general aspects of the CP-violating effects on the baryon asymmetry of the Universe (BAU) and electric dipole moments (EDMs) in models extended by an extra Higgs doublet and a singlet, together with electroweak-interacting fermions.

Discrete Symmetries on the Light Front and a General Relation Connecting Nucleon Electric Dipole and Anomalous Magnetic Moments

, 2006
We consider the electric dipole form factor, F_3(q^2), as well as the Dirac and Pauli form factors, F_1(q^2) and F_2(q^2), of the nucleon in the light-front formalism. We derive an exact formula for F_3(q^2) to complement those known for F_1(q^2) and F_2(

Electric Octupole-Dependent Contributions to Optical Binding Energy

Physics
Contributions to the radiation-induced dispersion energy shift between two interacting particles dependent on the electric octupole moment are calculated using a physical picture in which moments induced by applied fluctuating electromagnetic fields are ...

Sensitivity on the Dipole Moments of the τ-Neutrino at e+e- Colliders: ILC and CLIC

Advances in High Energy Physics, 2014
We study the sensitivity on the anomalous magnetic and electric dipole moments of the τ-neutrino at a high-energy and high-luminosity linear electron positron collider, such as the ILC or CLIC, through the reaction e+e-→νν̅γ.
