The non-Abelian property of quantum chromodynamics (QCD) permits the existence of new types of hadrons, such as glueballs, hybrids, and multiquark states, which are beyond conventional mesons and baryons in the constituent quark model [1–3]. In particular, the glueball is a unique particle formed via the interaction among gauge boson particles. Lattice quantum chromodynamics (LQCD) pre- dicts that the ground state of a pseudoscalar glueball has a mass around 2.3–2.6 GeV/c*2 [4–8]. The radiative decay of the J/ψ meson is a gluon-rich process and is therefore regarded as an ideal place for searching and studying glueballs.
