Meson correlators in finite temperature lattice QCD

We analyze temporal and spatial meson correlators in quenched lattice QCD at T>0. Below Tc we observe little change in the meson properties as compared with T50. Above Tc we observe new features: chiral symmetry restoration and signals of plasma formation, but also an indication of persisting ‘‘mesonic’’ ~metastable! states and different temporal and spatial ‘‘masses’’ in the mesonic channels. This suggests a complex picture of QGP in the region (1 ‐1.5)Tc .
