Abstract: (Springer)
The correlators of currentsQ,γvγ5Q,q andQ being correspondingly light and heavy quark fields, in hot hadronic matter are investigated by means of finite temperature QCD sum rules. AtT≳ 100 MeV the modification of the effective spectrum parameters takes place, similar to that found earlier in the correlators of light quark currents. AtT≳150 MeV the form of the spectrum is obtained, which indicates an appearance in hadronic matter of quasifree quarks with nonzero mass being fixed by the value of the quark condensate 〈q〉 (T).- MATTER: HADRONIC
