摘要：We study the properties of charmonium states at finite temperature in quenched QCD on isotropic lattices. We measured charmonium correlators using non-perturbatively O(a) improved clover fermions on fine (a =0.01 fm) lattices with a relatively large size of 1283×96, 1283×48, 1283× 32 and 1283×24 at 0.73 Tc, 1.46 Tc, 2.20 Tc and 2.93 Tc, respectively. Our analysis suggests that J/y is melted already at 1.46 Tc and hc starts to dissolve at 1.46 Tc and does not exist at higher temperatures. We also identify the heavy quark transport contribution at the spectral function level for the first time.
