The triple gauge-boson couplings, alpha(W phi), alpha(W) and alpha(B psi), have been measured using 34 semileptonically and 54 hadronically decaying W(+)W(-) candidate events. The events were selected in the data recorded during 1996 with the ALEPH detector at 172 GeV, corresponding to an integrated luminosity of 10.65 pb(-1). The triple gauge-boson couplings have been measured using optimal observables constructed from kinematic information of W(+)W(-) events. The results are in agreement with the Standard Model expectation.

1998
Abstract
The triple gauge-boson couplings, alpha(W phi), alpha(W) and alpha(B psi), have been measured using 34 semileptonically and 54 hadronically decaying W(+)W(-) candidate events. The events were selected in the data recorded during 1996 with the ALEPH detector at 172 GeV, corresponding to an integrated luminosity of 10.65 pb(-1). The triple gauge-boson couplings have been measured using optimal observables constructed from kinematic information of W(+)W(-) events. The results are in agreement with the Standard Model expectation.
