We make a theoretical study of the J/Psi decays into \omega\pi\pi, \phi\pi\pi, \omega K \bar{K} and \phi K\bar{K} using the techniques of the chiral unitary approach stressing the important role of the scalar resonances dynamically generated through the final state interaction of the two pseudoscalar mesons. We also discuss the importance of new mechanisms with intermediate exchange of vector and axial-vector mesons and the role played by the OZI rule in the J/\Psi\phi\pi\pi vertex, quantifying its effects. The results nicely reproduce the experimental data for the invariant mass distributions in all the channels considered.

However, for strong production processes, we deduced in Ref. [ref] , following a similar procedure as Roca, Palomar, Oset, and Chiang in Ref. [ref] , a relation between the production amplitude P and the scattering amplitude T, reading [equation] which, using Eqs. ([ref]) and ([ref]), can also be written as [equation] For the latter expression we find, by the use of Eq. ([ref]), that the production amplitude of Eq. ([ref]) tends to zero when $E→E_NL$.

This is why the peak of the $f_0(980)$ state become narrow when we add the coupled channel of $ηη$, which is different from the interference effects in the case of narrow $σ$ state in the $J/ψ→p p̅ π^+π^-$ decay [ref] and the $J/ψ→ωππ$ decay [ref] .

For the $ℓ$-th partial wave of the production amplitude ([ref]), we then obtain [equation] This is exactly the generic form of the production amplitude used in a paper by Roca, Palomar, Oset and Chiang [ref] , when at the $f_0$(600) resonance the inelastic contribution $KK→ππ$ is neglected, resulting in $a∝T/V$.

Nonetheless, the triangle singularities in this process have the same origin as the prominent one for the $J/ψ→π^0ηϕ$, and deserve to be studied in more detail to reveal another aspect of the $J/ψ→π^0π^0ϕ$ process in addition to the $ππ$ distribution that has been extensively studied both experimentally [ref] and theoretically [ref] .
