W Z production at eγ colliders and anomalous quartic WWZγ coupling

We investigate the constraints on the anomalous quartic W+W- Z gamma gauge boson coupling through the process e(-)gamma -> v(e) W(-)Z. Considering incoming beam polarizations and the longitudinal and transverse polarization states of the final Wand Z boson we find 95% confidence level limits on the anomalous coupling parameter a(n) with an integrated luminosity of 500 fb(-1) and root s = 0.5, 1 TeV energies. We show that initial beam and final state polarizations improve the sensitivity to the anomalous coupling by up to factors of 2-3.5 depending on the energy.
