Abstract

We report on measurements of mass and total decay width of the W boson and of triple-gauge-boson couplings, γWW and ZWW, with the L3 detector at LEP. W-pair events produced in e⁺e^- interactions between 161GeV and 172GeV centre-of-mass energy are selected in a data sample corresponding to a total luminosity of 21.2 pb^-1. The mass and total decay width of the W boson are determined to be M_w = 80.75^+0.26 _-0.27 (exp.) ± 0.03 (LEP) GeV and Γ_w = 1.74 ^+0.88 _-0.78 (stat.) ± 0.25 (syst.) GeV, respectively. Limits on anomalous triple-gauge-boson couplings, γWW and ZWW, are determined, in particular - 1.5 < δ_z < 1.9 (95% CL), excluding vanishing ZWW coupling at more than 95% confidence level.
