摘要：
We analyze temporal and spatial meson correlators in quenched lattice QCD at T greater than or equal to0. Below T-c Eve observe little change in the meson properties as compared with T=0. Above T-c 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)T-c.
