- Abstract: In this talk we present an interpretation for the experimental data available on two different processes, namely, J/Ψ → φπ +π −, J/Ψ → γωφ, which seem to indicate existence of two new resonances with the same quantum numbers (J πc = 0 ++,I = 0) and very similar mass ( 1800 MeV) but with very different decay properties. However, our studies show that the peak structure found in the ωφ invariant mass, in J/Ψ → γωφ, is a manifestation of the well known f0(1710) while the cross section enhancement found in J/Ψ → φπ +π − is indeed a new f0 resonance with mass near 1800 MeV. We present an explanation for the different decay properties of these two scalar resonances.
