Flavor symmetry correction to the "naive" Zweig rule for the scalar meson flavor singlet

Abstract: We present flavour-symmetric couplings for the OZI-allowed three-meson vertices of effective meson theories, which, for the case of the two-meson channels to which the flavour-singlet scalar meson couples, are endowed with a correction factor with respect to the standard formula.
