Abstract

We have measured charged particle pair production in two-photon scattering at the e⁺e^- storage ring PETRA. While the main source of such events is the production of lepton pairs, the presence of an additional process is clearly indicated by the measured invariant mass distribution of the two particles and their angular distributions. We determine that the excess is mainly due to the decay f⁰(1270)→π⁺π^-. We derive a width Γ(f⁰→γγ)=3.2±0.2±0.6 keV (statistical and systematic). © 1981 Springer-Verlag.
