概要

• 論文の詳細を見る

• The π~0π~0 mass spectra and angular distributions around the KK^-p^--threshold and at 1.5 GeV in pp^-(at rest)→3π~0 in the Crystal Barrel experiment are reanalyzed by applying a new method, which is consistent with the unitarity of the S-matrix and is expressed directly in terms of resonance parameters.The effects of light σ-meson production are clearly seen to improve the fit with σ in comparison with the fit without σ.
