Chiral symmetry restoration in σ-meson production in hadronic processes
Some puzzles about the nature and properties of the lightest scalar meson, σ or f0(500), are analyzed in the paper. We studied the σ-meson production both in N + N, N + d, etc., collisions and also in J/ψ, ψ(2S), ψ(3S), Υ(2S), etc., two-pion decays. The fundamental distinctions between the basic σ-...
