  "abstract": "Outline: 1. Introduction, 2. Confinement, chiral dynamics and light scalar mesons, 3. Chiral shielding of \\sigma(600), chiral constraints, \\sigma(600), f_0(980) and their mixing in \\pi\\pi\\to\\pi\\pi, \\pi\\pi\\to K\\bar K, and \\phi\\to\\gamma\\pi0\\pi0, 4. The \\phi meson radiative decays on light scalar resonances. 5. Why a0(980) and f0(980) are not the K\\bar K molecules. 6. Light scalars in \\gamma\\gamma collisions. Evidence for four-quark components of light scalars is given. The priority of Quantum Field Theory in revealing the light scalar mystery is emphasized.",
