Abstract：
In this paper we discuss the production and decay of the glueball candidate θ/f₂(1720) in the J/ψ radiation decay. We find that in order to explain the ratios x and y of the helicity amplitudes of the process J/ψ→γ+θ the contribution from two D-wave components (l=2,s=0,2) must be considered in addition to the S-wave component We also discuss the possible experimental test for the second D-wave component (l=2,s=2).
