摘要：
We study mesonic and baryonic correlation functions in the temporal directions in the vicinity of the critical temperature T similar or equal to T-c using the instanton liquid model, in which chiral symmetry restoration is driven by the formation of instanton-antiinstanton molecules. Although we find the signals for all hadronic poles to be drastically reduced, some hadronic states seem to survive the phase transition, as loosely bound U(N-f) x U(N-f) chiral multiplets for mesons and parity doublets for baryons.
