2 v 1 9 J un 1 99 5 Can hadrons survive the chiral phase transition ?

We study mesonic and baryonic correlation functions in the temporal directions in the vicinity of the critical temperature T ≃ 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)×U(N f) chiral multiplets in the plasma phase. These states are the 0 + − 0 − mesons (π, σ, η ′ , δ) and the N(1 2 +) − N(1 2 −) baryons.
