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→ℓi+ℓj- are considered, taking into account all tree-level contributions.
