Hadronic modes in the quark plasma with an internal symmetry
  We show that requiring the quark partition function to be color singlet of SU(3) color gauge group leads to reordering the thermodynamic potential in terms of the colorless multi-quark modes ($q{\bar q}, qqq, {\bar q}{\bar q}{\bar q}, ...$) at any given temperature. In accord with the "preconfinement" property of QCD, under a suitable confining mechanism, these could evolve into color singlet hadrons/baryons at low temperatures. At fairly high temperatures these multi-quark color singlet structures propagate in the plasma like hadronic modes, just as in the more familiar low temperature phase. This suggests that there exists a strong correlation in the plasma at all temperatures which is in conformity with lattice results.
