Phys. Rev. Lett. 67, 1701–1704 (1991)Chiral symmetry in hot QCDReceived 17 June 1991; published in the issue dated 23 September 1991 Recent lattice calculations of static hadronic-screening lengths and the quark-number susceptibility are interpreted in terms of a simple constituent quark model. The conclusion is that just above Tc the nature of the hadronic modes is rather well described in terms of elementary π and σ, as well as light-quark, modes. Hence chiral symmetry in the absence of symmetry-breaking terms is realized through massless quarks rather than through parity doubling. © 1991 The American Physical Society URL:
