title = "Lepton and hadron pair production in two-photon reactions",

abstract = "We have measured the production of charged particle pairs in e+e− initiated two-photon reactions. The observed rates and invariant mass spectra agree with expectations from QED if a resonant π+π− production at the f0 mass is added. Assuming dominance of the helicity 2 production we obtain the width Γ(f0→γγ) = 2.3 ± 0.5 keV.",
