Charmonium spectral functions in Nf=2 QCD (2005)

Abstract We report on a study of charmonium at high temperature in 2-flavour QCD. This is the first such study with dynamical fermions. Using an improved anisotropic lattice action, spectral functions are extracted from correlators in the vector and pseudoscalar channels. No signs of mediuminduced suppression of the ground states are seen for temperatures up to 1.5Tc, while at T ~ 2Tc there are clear signs of modifications. The current systematic and statistical uncertainties in our data, in particular the relatively coarse lattice and small volume, do not allow us to draw a firm conclusion at this stage.
