A search is performed for a Higgs boson produced in association with a Z bo
son and decaying into two photons, using the L3 data collected at LEP at a
centre-of-mass energy of 189 GeV, All decay modes of the Z are considered.
No signal is observed and limits on the branching fraction of the Higgs bos
on decay into two photons as a function of the Higgs mass are derived assum
ing a Standard model production rate. A lower limit on the mass of a fermio
phobic Higgs is set at 94.9 GeV at 95% confidence level. (C) 2000 Elsevier
