Abstract
We study the mechanism of production of the light scalar mesons in the [Formula: see text] decays: [Formula: see text], and compare it with the mechanism of production of the light pseudoscalar mesons in the [Formula: see text] decays: [Formula: see text]. We show that the [Formula: see text] transition is negligibly small in comparison with the [Formula: see text] one. As for the the f0(980) meson, the intensity of the [Formula: see text] transition is not more thirty percent from the intensity of the [Formula: see text] ([Formula: see text]) transition. So, the [Formula: see text] decay supports the previous conclusions about a dominant role of the four-quark components in the σ(600) and f0(980) mesons.
