EFT approach to the electron electric dipole moment at the two-loop level [PDF]

Journal of High Energy Physics, 2018
The ACME collaboration has recently reported a new bound on the electric dipole moment (EDM) of the electron, |de| < 1.1 × 10−29 e · cm at 90% confidence level, reaching an unprecedented accuracy level. This can translate into new relevant constraints on

Constraining EDM and MDM lepton dimension-five interactions in the electroweak sector

Physics Letters B, 2020
We investigate dimension-five Lorentz-violating (LV) nonminimal interactions in the electroweak sector, in connection with the possible generation of electric dipole moment (EDM), weak electric dipole moment (WEDM), magnetic dipole moment (MDM) and weak ...

Measuring the electric dipole moment of the electron in BaF [PDF]

European Physical Journal D : Atomic, Molecular and Optical Physics, 2018
We investigate the merits of a measurement of the permanent electric dipole moment of the electron (eEDM) with barium monofluoride molecules, thereby searching for phenomena of CP violation beyond those incorporated in the standard model (SM) of particle

Precision Measurement of the Electron's Electric Dipole Moment Using Trapped Molecular Ions. [PDF]

Physical Review Letters, 2017
We describe the first precision measurement of the electron's electric dipole moment (d_{e}) using trapped molecular ions, demonstrating the application of spin interrogation times over 700 ms to achieve high sensitivity and stringent rejection of ...

Fermion dipole moment and holography [PDF]

Journal of High Energy Physics, 2015
In the background of a charged AdS black hole, we consider a Dirac particle endowed with an arbitrary magnetic dipole moment. For non-zero charge and dipole coupling of the bulk fermion, we find that the dual boundary theory can be plagued with superluminal modes.

Exciting a chiral dipole moment in an achiral nanostructure [PDF]

Optica, 2018
Controlling the electric and magnetic dipole moments of optical nanostructures is a fundamental prerequisite for light routing and polarization multiplexing at the nanoscale.

Origin of the sphaleron dipole moment [PDF]

Physical Review D, 1994
By providing a suitable definition of the electromagnetic field off the Higgs vacuum, we show that within the sphaleron there is a monopole-antimonopole pair with quantized charges, and a loop of electromagnetic current. On integration of the relevant charges and currents over the interior in the limit of small $ _W$, we recover the standard formula ...

Laser Cooled YbF Molecules for Measuring the Electron's Electric Dipole Moment. [PDF]

Physical Review Letters, 2017
We demonstrate one-dimensional sub-Doppler laser cooling of a beam of YbF molecules to 100  μK. This is a key step towards a measurement of the electron's electric dipole moment using ultracold molecules.

General CPT-even dimension-five nonminimal couplings between fermions and photons yielding EDM and MDM

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.

Reduced Limit on the Permanent Electric Dipole Moment of ^{199}Hg. [PDF]

Physical Review Letters, 2016
This Letter describes the results of the most recent measurement of the permanent electric dipole moment (EDM) of neutral ^{199}Hg atoms. Fused silica vapor cells containing enriched ^{199}Hg are arranged in a stack in a common magnetic field.
