CompositeZ-boson and CP violation in the processe + e -→Zγ⋆

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

A detailed analysis ofZ, γ pairs production ine + e− annihilation is presented using helicity amplitudes for the processe + e−→Zγ with arbitrarye + e -→Zγ andZγZ⋆ couplings. The role of the CP violating anomalous couplings are discussed. The bounds for the anomalous form factors which follow from partial wave unitarity conditions are found.
