000330339 520__ $$aThere is presented a unified analysis of all available data on the decays $\Upsilon(mS)\to\Upsilon(nS)\pi\pi$ ($m>n$, $m=2,3,4,5,$ $n=1,2,3$), $J/\psi\to\phi(\pi\pi, K\overline{K})$, and $\psi(2S)\to J/\psi\pi\pi$ and the data on isoscalar $S$-wave processes $\pi\pi\to\pi\pi,K\overline{K},\eta\eta$. The multi-channel $\pi\pi$ scattering is described in our model-independent approach based on analyticity and unitarity and using an uniformization procedure. It is shown that the basic shape of dipion mass distributions in the two-pion transitions of both charmonia and bottomonia states are explained by an unified mechanism based on the contribution of the $\pi\pi$, $K\overline{K}$ and $\eta\eta$ coupled channels including their interference.
