Charmonium spectral functions in two-flavour QCD

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 2Tc, while the P-waves (χc0 and χc1) melt away below 1.3Tc.
