Description
We present recent results for correlators and spectral functions of mesons containing charm and beauty quarks below and above the deconfinement crossover. The results are obtained using anisotropic lattice QCD with 2+1 dynamical quark flavours. The high-temperature results are benchmarked against reconstructed correlators determined from the zero-temperature correlator, allowing us to disentangle temperature effects from the effects of the reduced range of the temporal correlator. In the open-charm sector, we find significant thermal modifications already below the deconfinement crossover, and no sign of any surviving bound states above T_c. For S-wave quarkonium, our results suggest that these states survive well into the QGP phase.
