Abstract

A search is performed for production of short-lived particles in e+e−→XY, with X→γγ and Y→f¯f, for scalar X and scalar or vector Y. Model-independent limits in the range of 25–60 femtobarns are presented on σ (e+e−→XY ) × B(X→γγ) × B(Y→f¯f) for centre-of-mass energies in the range 205–207 GeV. The data from all LEP centre-of-mass energies 88–209 GeV are also interpreted in the context of fermiophobic Higgs boson models, for which a lower mass limit of 105.5 GeV is obtained for a “benchmark” fermiophobic Higgs boson.
