Description :The XXIIIrd Internaitonal Symposium on Lattice Field Theory 25-30 July 2005 Trinity College, Dublin, Ireland
Abstract :We study the free energies of heavy quarks calculated from Polyakov loop correlation functions in full 2-flavour QCD using the p4-improved staggered fermion action. A small but finite baryon number density is included via Taylor expansion of the fermion determinant in the baryo-chemical potential m. For temperatures above Tc we extract Debye screening masses from the large distance behaviour of the free energies and compare their m-dependence to perturbative results.
