Deconfinement of Constituent Quarks and the Hagedorn Temperature
The overwhelming majority of theoretical papers on phase transition of hadronic matter H to quark gluon plasma (H ↔ QGP) ignores constituent quarks Q which we shall call below briefly valons (the term proposed by R.Hwa). The present paper is fundamentally based on the conception of those valons as real entities having the same quantum numbers as current quarks and the mass which was more than once calculated theoretically as some 300 MeV and used for explanation of experiments (e.g., see1). The possibility of existence of a special state of strong interacting matter, that of deconfined valon gas with still broken chiral symmetry, is discussed here.
