Abstract

The CP-conserving triple-gauge-boson couplings, g^Z ₁ , κ_γ, λ_γ, g^Z ₅ , κZ and λ_Z are measured using hadronic and semi-leptonic W-pair events selected in 629 pb^-1 of data collected at LEP with the L3 detector at centre-of-mass energies between 189 and 209 GeV. The results are combined with previous L3 measurements based on data collected at lower centre-of-mass energies and with the results from single-W production and from events with a single-photon and missing energy. Imposing the constraints κZ = g^Z ₁ - tan² θW(κ_γ- 1) and λZ = λ_γ, we obtain for the C and P conserving couplings the results: g^Z ₁ = 0.966 ± 0.033(stat) ± 0.015(syst), κ_γ= 1.013 ± 0.066(stat) ± 0.026(syst), λ_γ=-0.021 ±0.035(stat) ±0.017(syst).
