Abstract: (Springer)
A search for the hadronic decay of a hypothetical resonance S0 in the process e+e−→γ + hadrons at Z0 energies is reported. Particular care is taken to optimise the sensitivity to a scalar resonance decaying into bottom quarks, as expected for Higgs production, e+e−→Z0→H0 γ with, in the Standard Model or some of its extensions. No evidence for such a resonance is observed in a sample of about 5 million produced Z0’s. The results are interpreted in terms of models of non-standard Higgs production. An update of a search for a resonance produced in association with hadrons and the subsequent resonance decay into two photons is also presented.- electron positron: colliding beams
