Anomalous Quartic $WW\gamma \gamma$ and $ZZ\gamma \gamma$ Couplings in $e\gamma$ Collision With Initial Beams 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 $e\gamma \to W^{-}\gamma {\nu }_e$ and $e\gamma \to Z\gamma e$. 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 $a_0$ and $a_c$ with an integrated luminosity of 500 $f{b}^{-1}$ and $\sqrt{s}$=0.5, 1 TeV energies. Assuming the $W^{+}{W}^{-}\gamma \gamma$ 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.
