A measurement of trilinear gauge couplings using the DELPHI detector

A measurement of the Trilinear Gauge Boson Couplings is performed on the 53.0 pb-1 of data collected by the DELPHI experiment in e+e- collisions at a centre-of-mass energy of 183 GeV. The differential cross-sections of W pair events from the qq-barlν final state are analysed to determine the couplings Δg1z, λγ and Δκγ associated with the WWZ/WWγ vertex. The couplings describe the magnetic dipole moment and electric quadrupole moment of the W boson. The results are transformed in a measurement of the gyromagnetic ratio, expressed as g - 2 of the W. The measured coupling values, magnetic moment and electric moment as well as the g - 2 value agree with the Standard Model predictions. (author)
