Magnetic Johnson Noise Constraints on Electron Electric Dipole Moment Experiments [PDF]

open access: yesPhysical Review A, 2004
Magnetic fields from statistical fluctuations in currents in conducting materials broaden atomic linewidths by the Zeeman effect. The constraints imposed by this broadening on the design of experiments that measure the electric dipole moment of the electron are analyzed. Contrary to the predictions of Lamoreaux [S. K. Lamoreaux, Phys. Rev.

Effective field theory interpretation of lepton magnetic and electric dipole moments

open access: yesJournal of High Energy Physics, 2021
We perform a model-independent analysis of the magnetic and electric dipole moments of the muon and electron. We give expressions for the dipole moments in terms of operator coefficients of the low-energy effective field theory (LEFT) and the Standard ...

Neutrino dipole portal at electron colliders

open access: yesPhysics Letters B, 2022
We propose to search for a heavy neutral lepton (HNL), that is also known as sterile neutrino, in electron colliders running with the center-of-mass energies at few GeV, including BESIII, Belle II, and the proposed Super Tau Charm Factory (STCF).

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

open access: yesPhysics 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.

Lepton flavor violation, lepton (g − 2) μ, e and electron EDM in the modular symmetry

open access: yesJournal of High Energy Physics, 2022
We study the lepton flavor violation (LFV), the leptonic magnetic moments (g − 2) μ, e and the electric dipole moment (EDM) of the electron in the Standard-Model Effective Field Theory with the Γ N modular flavor symmetry. We employ the stringy Ansatz on

The metastable Q 3Δ2 state of ThO: a new resource for the ACME electron EDM search

open access: yesNew Journal of Physics, 2020
The best upper limit for the electron electric dipole moment was recently set by the ACME collaboration. This experiment measures an electron spin-precession in a cold beam of ThO molecules in their metastable $H\,{(}^{3}{{\rm{\Delta }}}_{1})$ state ...

Constraining CP-phases in SUSY: An interplay of muon/electron g − 2 and electron EDM

open access: yesNuclear Physics B, 2022
The minimal supersymmetric standard model (MSSM) with complex parameters can contribute sizably to muon/electron anomalous magnetic dipole moment (g−2) and electric dipole moment (EDM). The electron g−2 interplays with electron EDM; the muon g−2 can also

Quantum chemical insight into the effects of the local electron environment on T2*-based MRI

open access: yesScientific Reports, 2021
T2* relaxation is an intrinsic magnetic resonance imaging (MRI) parameter that is sensitive to local magnetic field inhomogeneities created by the deposition of endogenous paramagnetic material (e.g. iron).

Magnetic and electric dipole moments of the $H\ {}^3\Delta_1$ state in ThO [PDF]

open access: yes, 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).

Electron electric dipole moment in mirror fermion model with electroweak scale non-sterile right-handed neutrinos

open access: yesNuclear Physics B, 2018
The electric dipole moment of the electron is studied in detail in an extended mirror fermion model with the following unique features of (a) right-handed neutrinos are non-sterile and have masses at the electroweak scale, and (b) a horizontal symmetry ...
