Optimal observables for the measurement of three gauge boson couplings ine + e −→W + W −

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

We investigate the prospects of measuring anomalous couplings between gauge bosons at electron-positron-colliders with optimal observables. Such observables are shown to contain all information on the coupling parameters that can be extracted in a given reaction. Their sensitivity to the form factors in the general expressions of the triple gauge verticesWWZ andWW γ, includingCP violating terms and absorptive parts, is calculated in view of LEP2 and the NLC.
