Title: Anomalous quartic WW{gamma}{gamma} and ZZ{gamma}{gamma} couplings in e{gamma} collision with initial beam and final state polarizations

Abstract

The constraints on the anomalous quartic WW{gamma}{gamma} and ZZ{gamma}{gamma} gauge boson couplings are investigated through the processes e{gamma}{yields}W{sup -}{gamma}{nu}{sub e} and e{gamma}{yields}Z{gamma}e. Considering the longitudinal and transverse polarization states of the final W or Z boson and incoming beam polarizations we find 95% confidence level limits on the anomalous coupling parameters a{sub 0} and a{sub c} with an integrated luminosity of 500 fb{sup -1} and {radical}(s)=0.5, 1 TeV energies. Assuming the W{sup +}W{sup -}{gamma}{gamma} couplings are independent of the ZZ{gamma}{gamma} couplings we show that the longitudinal polarization state of the final gauge boson improves the sensitivity to anomalous couplings by a factor of 2-3 depending on energy and coupling. An extra enhancement in sensitivity by a factor of 1.3 comes from a set of initial beam polarizations.
