Abstract
In this talk experimental results on the non-resonant production of hadrons in soft γγ scattering are reviewed:
The measured cross sections for the production of hadron pairs by two photons are compared to theoretical predictions (QCD calculations above about 2 GeV). Analyses of four pion final states are reported, including an angular correlation analysis of ρ° ρ°, first results on ρ + ρ − production and the observation of a narrow structure in the four pion mass spectrum near 2.1 GeV.
The experimental results on the total hadronic cross section for photon-photon scattering are critically discussed.
