Abstract：
Recent results from BES and CLEOc experiments on hadron spectroscopy and charmonium decays using J/ψ, ψ′ and ψ′′ data samples collected in e⁺e^－ annihilation are reviewed,including the study of the scalar particles in J/ψ radiative and hadronic decays, as well as in ψ′ and χ_c0 hadronic decays, and the study of the “ρπ puzzle”in J/ψ,ψ′, and ψ′′ decays. The new results on the light scalars and the new information on the hadronic decays of the ortho-charmonium states shed light on the understanding of QCD.
