Περίληψη:
Measurements of the trilinear gauge boson couplings WWγ 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 ΔgZ 1 and Δκγ, the differences of the WWZ charge coupling and of the WWγ dipole coupling from their Standard Model values, and for λγ, the WWγ quadrupole coupling. A measurement of the magnetic dipole and electric quadrupole moment of the W is ,extracted from the results for Δκγ and λγ. The study uses data from the final states jjℓν, jjjj, ℓX, jjX and γX, 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. © 2001 Published by Elsevier Science B.V.
