Abstract

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