Measurement of triple gauge-boson couplings at 172 GeV

Measurement of triple gauge-boson couplings at 172 GeV

The triple gauge-boson couplings, α W Φ , α W and α B Φ , 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 10.6...

Zusammenfassung:The triple gauge-boson couplings, α W Φ , α W and α B Φ , 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.
