Abstract

Measurements of the trilinear gauge boson couplings WW gamma and WWZ an presented from data taken by DELPHI in 1997 at an energy of 183 GeV. From a study of the reactions e(+)e(-) --> W+W-, e(+)e(-) --> We nu and e(+)e(-) --> nu nu gamma, values are obtained for Delta g(1)(Z) and Delta kappa(gamma) the differences of the WWZ charge coupling and of the WW gamma dipole couplings from their Standard Model values, and for lambda(gamma) the WW gamma quadrupole coupling. The observations are consistent with the predictions of the Standard Model. (C) 1999 Elsevier Science B.V. All rights reserved.
