Description

Branching fractions of decays of heavy quarkonia $\psi(3770)$, $psi(4040)$, and $\Upsilon(10580)$ to the states $\pi^+\pi^-$, $K\bar K$, $\omega\pi^0$, $\omega\eta$, $\omega\eta^\prime$, $\rho\eta$, $\rho\eta^\prime$, $K^\ast\bar K+c.c.$, $\rho^+\rho^-$, $K^\ast\bar K^\ast$ etc are evaluated in the model of the Okubo - Zweig - Iizuka rule violation due to the real intermediate states of mesons with open open heavy flavors. The results are compared with existing experimental upper bounds.
