We compute charmonium spectral functions in 2-flavour QCD using the maximum
entropy method and anisotropic lattices. We find that the S-waves (J/ and c) survive
up to temperatures close to 2Tc, while the P-waves (c0 and c1) melt away below 1.3Tc.
1. INTRODUCTION
The fate of charmonium at high temperature has generated much interest the past
20 years [1]. Contrary to the original prediction that J/ production would be highly
