Аннотация: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-meson parameters found in various
hadronic processes can be explained most naturally by the chiral symmetry restoration in
intermediate excited hadronic resonances. In the present paper we discuss some impor-
tant aspects of chiral symmetry restoration in hadronic processes with interrelation to the
basic features of QCD.
