摘要：

We investigate the sea quark distribution around static quarks in the framework of lattice QCD by calculating the correlations of Polyakov loops with the local chiral condensate psi-psiBAR(r) and the color charge density psi(dagger)psi(r). A comparison of dynamical quarks in Kogut-Susskind and Wilson discretization is performed. We observe a restoration of chiral symmetry in the vicinity of color sources for both fermion regularization schemes as a consequence of gluon string formation. It turns out that virtual antiquarks screen static quarks as expected from QED.
