In our previous study, we calculated the transition from factors of
J/ψ→D(s)(∗) using the QCD sum rules. Based on the factorization
approximation, the obtained form factors can be applied to evaluate the weak
non-leptonic decay rates of J/ψ→D(s)(∗)+M, where M stands for a
light pseudoscalar or vector meson. We predict that the branching ratio for
inclusive non-leptonic two-body weak decays of J/ψ which are realized via
the spectator mechanism, can be as large as 1.3×10−8, in
particular, the branching ratio of J/ψ→Ds∗±+ρ∓ can reach
5.3×10−9. Such values will be marginally accessed by the ability of
BESIII which will begin running very soon.Comment: 16 pages, revTex4, 1 figur
