EXTRACTING W-BOSON COUPLINGS FROM THE E(+)E(-) PRODUCTION OF 4 LEPTONS

We consider the processes e(+)e(-) --> l(+)l(1-)nu<(nu)over bar>(1), including all the possible charged lepton combinations; with regard to measuring parameters characterizing the W boson. These reactions all proceed via virtual W pair production as well as a number of undistinguished s- and t-channel modes. In addition, some of the processes also have contributions from other diagrams of interest, those which contain the gamma WW or ZWW vertices with gauge bosons in the t channel. Consequently, the processes are sensitive to anomalous couplings such as kappa(gamma) and kappa(Z). We here calculate at what level these processes can be used to measure these anomalous couplings for the cases of e(+)e(-) colliders at 500 GeV and 1 TeV center-of-mass energies. Further, we present helicity information which should be useful in distinguishing between deviations of kappa(gamma), from its standard model value and deviations of kappa(Z).
