摘要：The search for quartic anomalous gauge couplings (QAGC) at LEP requires appropriate predictions for the radiative processes e+e− ! , e+e− ! qq and e+e− ! 4 fermions+. The current knowledge on dimension-six operators giving rise to QAGC is briefly reviewed, together with their implementation in event generators. The accuracy of calculations based on real approximations (used up to now for the LEP experimental analysis) is examined by comparing them with the available exact matrix element calculations.
