Z' and anomalous gauge coupling effects at LEP2 and their separation
A. A. Babich, A. A. Pankov, N. Paver
Abstract
In the case of the process e+e-μ+μ-, we study the sensitivity to either Z or anomalous gauge coupling effects of two new observables, σ+ and σ-, conveniently defined for such kind of analysis. We discuss general properties of the deviations of these observables from the Standard Model predictions, and derive the model-independent bounds on the relevant parameters allowed by present and foreseeable LEP2 data. We also discuss the possibility of separating the two kinds of effect.
