Effect of the ηη channel and interference phenomena in the two-pion transitions of charmonia and bottomonia
The basic shape of di-pion mass spectra in the two-pion transitions of both charmonia and bottomonia states is explained by a unified mechanism based on contributions of the ππ, KK̅, and ηη coupled channels including their interference. The role of the individual f0 resonances in shaping the di-pion mass distributions in the charmonia and bottomonia decays is considered.

The interference effects of multi-channel pion-pion scattering contributions to the final states of Ψ- and γ-meson family decays
It is shown that the basic shape of dipion mass distributions in the twopion transitions of both charmonia and bottomonia states are explained by an unified mechanism based on the contribution of the ππ, KK̄ and ηη coupled channels including their interference.
