Abstract.

The production of three electroweak gauge bosons in high-energy \(e^+e^-\) collisions offers a window on anomalous quartic gauge boson couplings. We investigate the effect of three possible anomalous couplings on the cross sections for \(W^+W^-\gamma\), \(Z^0Z^0\gamma\) and \(Z^0\gamma\gamma\) productions at LEP2 (\(\sqrt{s} = 200\) GeV) and at a future linear collider (\(\sqrt{s} = 500\) GeV). We find that the combination of energies and processes provides reasonable discrimination between the various anomalous contributions.
