Light Scalar Mesons from ϕ to ψ

The following topics are considered.1.Confinement, chiral dynamics, and light scalar mesons2.Chiral shielding of the σ(600)3.The ϕ meson radiative decays about nature of light scalar resonances4.The J/ψ decays about nature of light scalar resonances5.The a0(980)→γγ and f0(980)→γγ decays about nature of light scalar resonances6.New round in γγ→π+π−, the Belle dataArguments in favor of the four-quark model of the a0(980) and f0(980) mesons are given.
