摘要：
We compute charmonium spectral functions in 2-flavour QCD using the maximum entropy method and anisotropic lattices. We find that the S-waves (J / ψ and ηc) survive up to temperatures close to 2 Tc, while the P-waves (χc 0 and χc 1) melt away below 1.3 Tc. © 2006 Elsevier B.V. All rights reserved.
