摘要：

Measurements of the trilinear gauge boson couplings WW gamma and WWZ are presented using the data taken by DELPHI in 1998 at a centre-of-mass energy of 189 GeV and combined with DELPHI data at 183 GeV. Values are determined for Deltag(1)(Z) and Delta kappa (gamma), the differences of the WWZ charge coupling and of the WWgamma dipole coupling from their Standard Model values, and for hy, the WW gamma quadrupole coupling. A measurement of the magnetic dipole and electric quadrupole moment of the W is extracted from the results for Delta kappa (gamma) and lambda (gamma). The study uses data from the final states jjl nu, jjjj, lX, jjX and gammaX where j represents a quark jet, l an identified lepton and X missing four-momentum. The observations are consistent with the predictions of the Standard Model. (C) 2001 Published by Elsevier Science B.V.
