We compute charmonium spectral functions in 2-flavor QCD on anisotropic lattices using the maximum entropy method. Our results suggest that the S-waves ($J/\ensuremath{\psi}$ and ${\ensuremath{\eta}}_{c}$) survive up to temperatures close to $2{T}_{c}$, while the P-waves (${\ensuremath{\chi}}_{c0}$ and ${\ensuremath{\chi}}_{c1}$) melt away below $1.2{T}_{c}$.

• Holographic phase transitions at finite chemical potential (2007, background): “The second caveat is the fact that the very existence of many of the expected phases of QCD at finite chemical potential depend crucially on the fact that Nc = 3 (see e.g., [34, 35]).”
