摘 要：Quartic couplings, WWZZ, WWZγ WWγγ, and ZZγγ, were studied at LEP and Tevatron at energies at which the Standard Model predicts negligible contributions to multiboson production. Thus, to parametrize limits on these couplings, an effective theory approach is adopted which supplements the Standard Model Lagrangian with higher dimensional operators which include quartic couplings. The LEP collaborations chose the lowers dimensional representation of operators （dimension 6） which presumes the SU（2）xU（1） gauge symmetry is broken by means other than the conventional Higgs scalar doublet [1-3].
