摘要
We study lepton flavor observables in the Standard Model (SM) extended with all dimension-6 operators which are invariant under the SM gauge group. We calculate the complete one-loop predictions to the radiative lepton decays μ → eγ, τ → μγ and τ → eγ as well as to the closely related anomalous magnetic moments and electric dipole moments of charged leptons, taking into account all dimension-6 operators which can generate lepton flavor violation. Also the 3-body flavor violating charged lepton decays τ± → μ±μ+μ−, τ± → e±e+e−, τ± → e±μ+μ−, τ± → μ±e+e−, τ± → e∓μ±μ±, τ± → μ∓e±e± and μ± → e±e+e− and the Z0 decays Z0 → \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$ \ell_i^{+}\ell_j^{-} $\end{document} are considered, taking into account all tree-level contributions.
