Abstract

We obtain limits on the quartic neutral gauge bosons couplings ZγγγZ\gamma\gamma\gamma and ZZγγZZ\gamma\gamma using LEP 2 data published by the L3 Collaboration on the reactions e+eγγγ,Zγγe^+e^-\to \gamma\gamma\gamma, Z\gamma\gamma. We also obtain 95%95 \% C. L. limits on these couplings at the future linear colliders energies. The LEP 2 data induce limits of order 10510^{-5} GeV4GeV^{-4} for the ZγγγZ\gamma\gamma\gamma couplings and of order 10310^{-3} GeV2GeV^{-2} for the ZZγγZZ\gamma\gamma couplings, which are still above the respective Standard Model predictions. Future e+ee^+e^- linear colliders may improve these limits by one or two orders of magnitude.
