Abstract

A search is performed for production of short-lived particles in e(+)e(-) --> XY, with X --> gammagamma and Y --> f (f) over bar, for scalar X and scalar or vector Y. Model-independent limits in the range of 25-60 femtobarns are presented on a(e(+)e(-) --> XY) x B(X --> gammagamma) x B(Y --> f (f) over bar) for centre-of-mass energies in the range 205-207 GeV The data from all LEP centre-of-mass energies 88209 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.
