Abstract
The spectral functions of QCD can give us insight into properties of hadrons, and they are useful
in probing the QCD vacuum. I will discuss the correlators and spectral functions of charmonium
in high temperature two flavour QCD. The spectral functions have been obtained using the Maximum
Entropy Method from anisotropic lattice data using the conserved vector current. This work
has been done as part of the FASTSUM collaboration. We find that the spectral functions for zero
momentum are stable. At non-zero momentum the spectral functions are less stable but still produce
resonance and transport peaks. This work is part of our programme to calculate the heavy
quark diffusion constant.
