Abstract
Using a hybrid molecular-dynamics simulation of lattice QCD we measure the spatial screening lengths of local meson and baryon operators with two flavors of Kogut-Susskind fermions. In the high-temperature phase the meson and nucleon screening lengths are parity doubled and their inverses are comparable to the zero-temperature masses. We construct chiral projections for the meson and nucleon propagators which demonstrate the chiral symmetry in a way independent of the extraction of masses from the propagators.Keywords
