Probing Higgs Couplings in e^+ e^- \to γγγ

Abstract

We investigate the existence of anomalous Higgs boson couplings, $H\gamma \gamma$ and $HZ\gamma$, through the analysis of the process $e^{+}{e}^{-}\to \gamma \gamma \gamma$ at LEP2 energies. We suggest some kinematical cuts to improve the signal to background ratio and determine the capability of LEP2 to impose bounds on those couplings by looking for a Higgs boson signal in this reaction.
