Abstract :
The π0π0 mass spectra and angular distributions around View the MathML source and at 1.5 GeV in View the MathML source in the Crystal Barrel experiment are reanalyzed by applying the new method, which is consistent with unitarity of S-matrix and expressed directly by resonance parameters. The effects of light σ-meson production are clearly seen to improve the fit with σ, in comparing with the fit without σ.
