Description: It is shown that the basic shape of dipion and KK̅ mass spectra in decays J/ψ→ϕ(ππ,KK̅), ψ (2S)→J/ψππ, Y(4260)→J/ψ π π and in the two-pion transitions of bottomonia states are explained by an unified ... More

Description: 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 ch ... More
