Anomalous Magnetic Dipole Moment \((g-2)\mu\) in 3-3-1 Model with Inverse Seesaw Neutrinos [PDF]
Communications in Physics, 2020 We will show that the recent experimental value of the anomalous magnetic moment (AMM) of the charged lepton m , denoted as \(a_mu (g-2)\mu/2\), can be explained successfully in a 3-3-1 model with right handed neutrino adding new heavy \(SU (3)_L\) neutrinos singlets. Allowed regions satisfying the recent AMM data are illustrated numerically.

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

Muon and electron g − 2 and lepton masses in flavor models
Journal of High Energy Physics, 2020 The stringent experimental bound on μ → eγ is compatible with a simultaneous and sizable new physics contribution to the electron and muon anomalous magnetic moments (g − 2)ℓ (ℓ = e, μ), only if we assume a non-trivial flavor structure of the dipole ...

Charged lepton flavor violating radiative decays l i → l j γ in G2HDM
Journal of High Energy Physics, 2023 We compute the electromagnetic form factors of the l i l j γ vertex at one-loop level in the minimal G2HDM which has a sub-GeV vector dark matter candidate.

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

Quark electric dipole moment induced by magnetic field [PDF]
, 2010 We show numerically that quarks develop an electric dipole moment in the direction of a sufficiently intense magnetic field due to local fluctuations of topological charge.

A large muon EDM from dark matter
Journal of High Energy Physics, 2023 We explore a model of dark matter (DM) that can explain the reported discrepancy in the muon anomalous magnetic moment and predict a large electric dipole moment (EDM) of the muon.

Preparations for a search of the muon EDM at PSI [PDF]
EPJ Web of Conferences, 2023 Electric dipole moments (EDMs) of fundamental particles violate time invariance and the combined symmetry of charge and parity (CP). The existence of a large muon EDM (muEDM) is made plausible by tensions with Standard Model predictions for semileptonic ...
