Lepton dipole moments in supersymmetric low-scale seesaw models [PDF]
, 2013 We study the anomalous magnetic and electric dipole moments of charged leptons in supersymmetric low-scale seesaw models with right-handed neutrino superfields.

Lepton $$g-2$$ g - 2 and W-boson mass anomalies in the DFSZ axion model
European Physical Journal C: Particles and Fields, 2023 With regard to the leptonic magnetic dipole moment anomaly as well as the W-boson mass excess, we study the DFSZ axion model. Considering theoretical and experimental constraints, we show that the muon and electron $$g-2$$ g - 2 anomalies can be ...

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 ...

Smith–Purcell radiation of a vortex electron
New Journal of Physics, 2021 A wide variety of emission processes by electron wave packets with an orbital angular momentum ℓℏ , called the vortex electrons, can be influenced by a nonparaxial contribution due to their intrinsic electric quadrupole moment.

Thermodynamic approach to electric quadrupole moments [PDF]
Phys. Rev. B 102, 235149 (2020), 2020 Higher-rank electric/magnetic multipole moments are attracting attention these days as candidate order parameters for exotic material phases. However, quantum-mechanical formulation of those multipole moments is still an ongoing issue. In this paper, we propose a thermodynamic definition of electric quadrupole moments as a measure of symmetry breaking,

Supersymmetric Relations Among Electromagnetic Dipole Operators
, 2001 Supersymmetric contributions to all leptonic electromagnetic dipole operators have essentially identical diagramatic structure. With approximate slepton universality this allows the muon anomalous magnetic moment to be related to the electron electric ...

Constraining active-sterile neutrino transition magnetic moments at DUNE near and far detectors
Journal of High Energy Physics, 2021 We consider the sensitivity of the DUNE experiment to a heavy neutral lepton, HNL (also known as sterile neutrino) in the mass range from a few MeV to a few GeV, interacting with the Standard Model via a transition magnetic moment to the active neutrinos,
