    • The OZI rule is easy formulated at the quark level as the suppression of the three-gluon annihilation [13]. At the level of real intermediate states, it is formulated as the condition of compensation of their contribution to the OZI rule violating amplitude, cf. H. J. Lipkin, Nucl. Phys. B291, 720 (1987);
