General CPT-even dimension-five nonminimal couplings between fermions and photons yielding EDM and MDM [PDF]
Physics Letters B, 2016 In this letter, we examine a new class of CPT-even nonminimal interactions, between fermions and photons, deprived of higher order derivatives, that yields electric dipole moment (EDM) and magnetic dipole moment (MDM) in the context of the Dirac equation.

Magnetic and electric dipole moments of the $H\ {}^3Δ_1$ state in ThO [PDF]
Phys. Rev. A 84, 034502 (2011), 2011 The metastable $H \ {}^3\Delta_1$ state in the thorium monoxide (ThO) molecule is highly sensitive to the presence of a CP-violating permanent electric dipole moment of the electron (eEDM). The magnetic dipole moment $\mu_H$ and the molecule-fixed electric dipole moment $D_H$ of this state are measured in preparation for a search for the eEDM.

Magnetic dipole moment of the electron [PDF]
arXiv, 2008 We present a model which determines the correct value of the magnetic dipole moment of the electron. By this, we find a physical meaning for the electron spin.

Supersymmetric phases, the electron electric dipole moment and the muon magnetic moment [PDF]
, 2001 The electron electric dipole moment (d_e) and the muon magnetic moment anomaly (a_{\mu}) recently observed at BNL are analyzed within the framework of SUGRA models with CP violating phases at the GUT scale.

Electron and muon anomalous magnetic dipole moment in a 3–3–1 model [PDF]
Journal of High Energy Physics, 2017 We calculate, in the context of a 3–3–1 model with heavy charged leptons, constraints on some parameters of the extra particles in the model by imposing that their contributions to both the electron and muon (g − 2) factors are in agreement with ...

Noncommutative QED and Anomalous Dipole Moments [PDF]
JHEP 0008:045,2000, 2000 We study QED on noncommutative spaces, NCQED. In particular we present the detailed calculation for the noncommutative electron-photon vertex and show that the Ward identity is satisfied. We discuss that in the noncommutative case moving electron will show {\it electric} dipole effects.

Flavor-Changing Magnetic Dipole Moment and Oscillation of a Neutrino in a Degenerate Electron Plasma [PDF]
, 1995 The standard model prediction for a magnetic dipole moment of a neutrino is proportional to the neutrino mass and extremely small. It also generates a flavor-changing process, but the GIM mechanism reduces the corresponding amplitude. These properties of

Multiconfiguration Dirac-Hartree-Fock calculations of atomic electric dipole moments of 225^Ra, 199^Hg, and 171^Yb [PDF]
arXiv, 2013 The multiconfiguration Dirac-Hartree-Fock (MCDHF) method has been employed to calculate atomic electric dipole moments (EDM) of 225^Ra, 199^Hg, and 171^Yb. For the calculations of the matrix elements we extended the relativistic atomic structure package GRASP2K.

Considerations about the measurement of the magnetic moment and electric dipole moment of the electron [PDF]
arXivThe goal of the measurement of the magnetic moment of the electron $\mu$, is to experimentaly determine the gyromagnetic ratio. The factor $g/2$ is computed by the accurate measurement of two frequencies, the spin precession frequency $\nu_s$, and the cyclotron frequency $\nu_c$, and is defined as $\nu_s/\nu_c=g/2$. These experiments are performed with

The shadow of dark matter as a shadow of string theory
European Physical Journal C: Particles and Fields, 2019 We point out that string theory can solve the conundrum to explain the emergence of an electroweak dipole moment from electroweak singlets through induction of those dipole moments through a Kalb–Ramond dipole coupling.
