چکیده

It is presented a critical consideration of all unusual properties of the scalar a 0 (980) and f 0 (980)-mesons in the four-quark, two-quark and molecular models. The arguments are adduced that the four-quark model is more preferable. It is discussed the complex of experiments that could finally resolve this issue.

The following topics are considered. 1. Confinement, chiral dynamics and light scalar mesons. 2. φ-meson radiative decays about nature of light scalar resonances. Arguments in favor of the four-quark model of the a 0 (980) and f 0 (980) mesons are given. To discuss actually the nature of the putative nonet of the light scalar mesons: the red putative f 0 (600) (or σ(600)) and κ(700−900) mesons ...

The branching ratio of the φ meson to γK 0 ¯ K 0 is calculated to be 5 × 10 −8 in a scheme which takes into account the different isospin channels involved, I = 0, 1 with the resonant, f 0 (980), a 0 (980), and non resonant contributions. The study of the process φ → γK 0 ¯ K 0 is an interesting subject since it provides a background to the reaction φ → K 0 ¯ K 0. This latter process has been p...
