Description
Given the solution of Nf=2 QCD on the lattice
with a chirally symmetric Dirac operator
and symmetry classification of the QCD Lagrangian
we identify the following three physically different regimes
of QCD.
Up to the pseudo-critical temperature Tc
the QCD matter is a hadron gas with broken chiral symmetries.
From the hadron gas regime below Tc there is a crossover to
a regime with chiral and chiral-spin symmetries, where chirally
symmetric quarks are bound by the chromo-electric component
of gluonic field without the chromo-magnetic contributions. From
temperatures 500 - 550 MeV there is a
smooth evolution to the quark-gluon plasma regime with weakly interacting
quarks and where only chiral symmetries survive.
