| dc.description | Outline: 1. Introduction, 2. Confinement, chiral dynamics and light scalar mesons, 3. Chiral shielding of the σ(600), chiral constraints (the CGL band), the σ(600) and the f0(980) in ππ->ππ, ππ->KKbar, ϕ->γ\pi0\pi0, 4. The ϕmeson radiative decays on light scalar resonances, 5. Light scalars in γγcollisions. Evidence for four-quark components of light scalars is given. The priority of Quantum Field Theory in revealing the light scalar mystery is emphasized. | |
| dc.description | Plenary talk given by N.N. Achasov at PHIPSI08, Frascati, April 9, 2008. In spite of allegations in the papers arXiv:0806.0328 (M.R. Pennington) and arXiv:0803.3389 (M.R. Pennington et al.), the model of PRD 77 (2008) 074020 (N.N. Achasov, G.N. Shestakov) reproduces γγ->\pi0\pi0 above 800 MeV (see Sec. V, Fig. 5, in PRD and Sec. 20, Fig. 9, in this talk) | |
