Abstract

The triple gauge-boson couplings involving the W are determined using data samples collected with the ALEPH detector at mean centre-of-mass energies of 183GeV and 189GeV, corresponding to integrated luminosities of 57 pb-1 and 174, pb-1, respectively. The couplings, gZ1, and λγ, are measured using W-pair events, single-W production and single-γ production. Each coupling is measured individually with the other two couplings fixed at their standard model value. Including ALEPH results from lower energies, the 95% confidence level intervals for the deviation to the standard model are -0.087 < ΔgZ1 < 0.141, -0.200 < ΔKγ < 0.258, and - 0.062 < λγ < 0.147. Fits are also presented where two or all three couplings are allowed to vary. In addition, W-pair events are used to set limits on the C-or P-violating couplings gV4, gV5, K̃V, and λV, where V denotes either γ or Z. No deviations from the standard model expectations are observed.
