Studies on the anomalous magnetic and electric dipole moments of the tau-neutrino in pp collisions at the LHC [PDF]
The European Physical Journal A, 2019 In this paper the production cross section $pp\rightarrow (γ, Z) \to ν_τ\bar ν_τγ+X$ in $pp$ collisions at $\sqrt{s}=8, 13, 14, 33TeV$ is presented. Furthermore, we estimate bounds at the $95\%C. L.$ on the dipole moments of the tau-neutrino using integrated luminosity of ${\cal L}=20, 50, 100, 200, 500, 1000, 3000 fb^{-1}$ collected with the ATLAS ...

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 ...

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

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
