Title: Interpreting the peak structures around 1800 MeV in the BES data on J/Ψ→φπ{sup +}π{sup −}, J/Ψ→γωφ

In this talk we present an interpretation for the experimental data available on two different processes, namely, J/Ψ→φπ{sup +}π{sup −}, J/Ψ→γωφ, which seem to indicate existence of two new resonances with the same quantum numbers (J{sup πc} = 0{sup ++}, I = 0) and savery 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 f{sub 0}(1710) while the cross section enhancement found in J/Ψ→φπ{sup +}π{sup −} is indeed a new f{sub 0} resonance with mass near 1800 MeV. We present an explanation for the different decay properties of these two scalar resonances.
