Studies of the θ(1720) Wide Resonance in J/ψ Hadronic Decays

Abstract：

In this paper the structure of the θ(1720) wide resonance produced in J/ψ hadronic decays is studied by using the generalized moment analysis. Since the production yield of the f₂'(1525) is very small, we may neglect the influence of the f₂'(1525) is larger we must consider the coherence effects of the f₂'(1525) for the process J/ψ→ωθ(1720). Whereas the production yield of the f₂'(1525) is larger we must consider the coherence effects of the f₂'(1525) for the process J/ψ→ωθ(1720). From the studies of the above two processes and the corresponding J/ψ radiative decay process we are able to understand the structure of the θ(1720) wide resonance better.
