Anomalous quartic couplings in W+W-γ, Z0Z0γ and Z0γγ production at present and future e+e- colliders

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(0)Z(0)gamma and Z(0)gamma gamma productions at LEP2 (root s = 200 GeV) and at a future linear collider (root s = 500 GeV). We find that the combination of energies and processes provides reasonable discrimination between the various anomalous contributions.
