On the Thermodynamics of a Heavy Quark-Antiquark Pair
D. Antonov, S. Domdey, H. -J. Pirner
Abstract
Thermodynamics of a heavy quark-antiquark pair in SU(3)-QCD is studied below the deconfinement critical temperature, Tc. In the quenched case, a model of the string passing through heavy valence gluons yields a correct estimate of Tc and a behavior of the string tension near Tc. For two light flavors, entropy and internal energy can be obtained from the partition function of heavy-light mesons and baryons. They are in a good qualitative agreement with the lattice results.
