Mystery of J/PSI->γ+rhorho, J/PSI->γ+ωω and J/PSI->γ+γrho0 decays
Description
It is shown that the pseudoscalar structure discovered in the rhorho and ωω mass spectra near 1.7 GeV in J/PSI->γ+rhorho and J/PSI->γ+ωω decays can be explained by the decays l(1440, 0-)->rhorho and l(1440, 0-)->ωω on the resonance tail. The importance of the J/PSI->γ+γphi decay research is emphasized. We obtain (predict) BR(J/PSI->γ+l)approx.=9x10-3 which testifies in favour of the glueball assignment of the l(1440, 0-) meson.
