Popis:	Here, we treat the high-energy production process\(e\bar v_e \to W^ - Z^0 \), allowing for gauge boson compositeness, using two approaches: (a) through an anomalousW boson weak magnetic moment parameterkz, and (b) through a modification of theW propagator andWWZ vertex by a form factor depending on a compositeness scale parameter Λ. We give the angular differential and total cross-section for different values ofkz (approach (a)), and different values of Λ (approach (b)). A clear deviation from the standard model result is observed in both cases.
