Can hadrons survive the chiral phase transition ?

Abstract

We study mesonic and baryonic correlation functions in the temporal directions in the vicinity of the critical temperature TTcT\simeq T_c using the instanton liquid model. In this model 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(Nf)×U(Nf)U(N_f)\times U(N_f) chiral multiplets in the plasma phase. These states are the 0+00^+ - 0^- mesons (π,σ,η,δ)(\pi,\sigma,\eta',\delta) and the N(12+)N(12)N(\frac{1}{2}^+) - N(\frac{1}{2}^-) baryons.
