Magnetic Johnson Noise Constraints on Electron Electric Dipole Moment Experiments [PDF]
Physical 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
Journal 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
Physics 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).

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.

Lepton flavor violation, lepton (g − 2) μ, e and electron EDM in the modular symmetry
Journal 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
New 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
Nuclear 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
Scientific 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]
, 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).
