  Using non-perturbative lattice method we studied hadronic screening
correlators above and immediately below the deconfinement transition
temperature, Tc, in the quenched approximation with lattice spacing of 1/(8T)
using clover improved Wilson fermions. Simulations were performed at
temperatures T /Tc = 0, 0.95 and 1.5. Mesonic screening correlators show no
statistically significant thermal effects below Tc, and clear evidence for
weakly interacting quarks above Tc . Baryon screening correlators yield similar
physics above Tc, but show precursor effects for chiral symmetry restoration
below Tc .
