  • We present lattice QCD results on heavy quark free energies, extract from its temperature dependence entropy and internal energy contributions, and discu ss the onset of medium effects that lead to screening of static quark-antiquark sources in a thermal medium. Most results are obtained in (2+1)-flavour QCD on a line of constant physics with almost re alistic quark masses and compared to previous results from 2-flavor QCD as well as pure gauge the ory. Furthermore, we discuss results on the… CONTINUE READING
