Flavour-symmetry correction to the ``naive'' Zweig rule for the scalar-meson flavour-singlet
Abstract
Description
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.
