Abstract

We report first results for spectral functions of charmonium in 2-flavour QCD. The spectral functions are determined from vector and pseudoscalar correlators on a dynamical, anisotropic lattice. J/ and c are found to survive well into the deconfined phase before melting away at T . 2Tc. Current systematic uncertainties prevent us from drawing any definite conclusions at this stage.
