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 for...

By using a product configurator customers can “experience” how the product can be adapted in accordance to individual needs and preferences.
