Analysis of Y(4660) and Related Bound States with QCD Sum Rules

<正> In this article,we take the vector charmonium-like state Y（4660） as a Ψ'f0（980） bound state （irrespective ofthe hadro-charmonium and the molecular state） tentatively,and study its mass using the QCD sum rules.The numericalvalue MY = 4.71±0.26 GeV is consistent with the experimental data.Considering the SU（3） symmetry of the light flavorquarks and the heavy quark symmetry,we also study the bound states Ψ′σ（400-1200）,γ′″ f0（980）,and γ′″σ（400-1200）with the QCD sum rules,and make reasonable predictions for their masses.
