We study the properties of charmonium states at finite temperature in quenched QCD on isotropic lattices. We measured charmonium correlators using non-perturbatively $\cO(a)$ improved clover fermions ...

We report recent results on charmonium spectroscopy and decay from the CLEO-c experiment at the Cornell electron-positron storage ring accelerator, CESR. Most of the results are based on the analysis ...
Using ~14×106 ψ(2S) and ~58×106 J/ψ data collected at BESⅡ/BEPC, the branching fraction of ψ(2S)→Ω－Ω+ is measured with about 5σ statistical significance. The Λ electric dipole and Λ decay parameter ar...
In this proceeding, we propose to directly measure the a00(980)-f0(980) mixing in J/ψ→φ f0(980)→φa00(980) and χc1→π0φa00(980)→π0f0(980) with the upgraded Beijing Electron Positron Collider(BEPCII) wit...
Using the method of QCD sum rules, we estimate the energy of the lowest hybrid charmonium state, and find it to be at the energy of the Ψ′(2S) state, about 600 MeV above the J/Ψ(1S) state. Since...
