Abstract：
In this paper the structure of the θ(1720) wide resonance produced in J/ ψhadronic decays is studied by using the generalized moment analysis. Since the production yield of the f ₂'(1525) is very small, we may neglect the influence of the f ₂'(1525) is larger we must consider the coherence effects of the f ₂'(1525) for the process J/ ψ→ ωθ(1720). Whereas the production yield of the f ₂'(1525) is larger we must consider the coherence effects of the f ₂'(1525) for the process J/ ψ→ ωθ(1720). From the studies of the above two processes and the corresponding J/ ψradiative decay process we are able to understand the structure of the θ(1720) wide resonance better.
