摘要
With the recent investigations of the g＊g＊-η（＇） transition form factor and mixing scheme, we present an updated study of the radiative decays J/ψ→η（＇）γ in perturbative QCD. The decays are taken as a test ground for the g＊g＊-η（＇） transition form factors and the η-η＇ mixing scheme. The form factors are found to be working for glunic η＇ production and the mixing angle is constrained to be φ = 35.1°±1 0.8°.
