Search for anomalous couplings in the Higgs sector at LEP

We search for a Higgs particle with anomalous couplings in the e + e − →H γ , e + e − →HZ and e + e − →He + e − processes with the L3 detector at LEP. We explore the mass range 70 GeV

electron positron: colliding beams
electron positron: annihilation
Higgs particle: electroproduction
photon: associated production
Z0: associated production
Higgs particle: coupling
Higgs particle: decay modes
Higgs particle: width
Higgs particle: mass
channel cross section: branching ratio
