Searches for clean anomalous gauge coupling effects at present and futuree+e−colliders

Abstract
We consider the virtual effects of a general type of anomalous (triple) gauge coupling on various experimental observables in the process of electron-positron annihilation into a final fermion-antifermion state. We show that the use of a recently proposed "Z-peak subtracted" theoretical description of the process allows us to reduce substantially the number of relevant parameters of the model, so that a calculation of observability limits can be performed in a rather simple way. As an illustration of our approach, we discuss the cases of future measurements at the CERN e+e collider LEP 2 and at a new 500 GeV linear collider.
