Anomalous Quartic Couplings in $\nu \bar{\nu} \gamma \gamma$ Production via WW-Fusion at LEP2

Abstract

The production of $\nu \bar{\nu} \gamma \gamma$ in high-energy $e^+e^-$ collisions offers a window on anomalous quartic gauge boson couplings. We investigate the effect of two possible anomalous couplings on the cross section for $\nu \bar{\nu} \gamma \gamma$ production via $WW$-fusion at LEP2 ($\sqrt{s} = 200$ GeV).
