Abstract：
Based on the physical implication of the unusually large mass scale and long live time characteristics of J/ψ particle and on the understanding of the requirement of glueball production,we proposed an alternative mechanism of glueball production in J/ψ radiative decay: the glueball G_b could be formed via fusion of a pair of constituent gluons which are emitted whenever the constituent charm quark and anti-quark in J/ψ transit into current charm quark and anti-quark,and remained current charm quark-pair annihilates into a photon. After a brief discussion of model parameters,we evaluate the partial width Γ J/ψ→Gb+γ,and compare it with the result from the mechanism where the glueball is produced via hadronazation of two emitted gluons in the J/ψ radiative decay.
