Abstract

We investigate the existence of anomalous Higgs boson couplings, HγγH\gamma\gamma and HZγHZ\gamma, through the analysis of the process e+e−→γγγe^+ 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.

Keywords

anomalous Higgs couplings H gamma gamma H Z gamma e+ e- -> gamma gamma gamma LEP2
