چکیده

Recent striking lattice results on bound states above T c are shown to be due to the strong nonconfining Q ¯ Q potential, predicted more than a decade ago in the framework of the field correlator method. Explicit expressions and quantitative estimates are given for Polyakov loop correlators and limiting temperature T D , when bound states dissociate. New theoretical predictions for glueballs and baryons above T c are given.

Recent striking lattice results on strong interaction and bound states above T c can be explained by the nonperturbative Q ¯ Q potential , predicted more than a decade ago in the framework of the field correlator method. Explicit expressions and quantitative estimates are given for Polyakov loop correlators in comparison with lattice data. New theoretical predictions for glueballs and baryons a...

1. Introduction. Models of QCD must confront nonperturbative phenomena such as confinement, dynamical chiral symmetry breaking (DCSB) and the formation of bound states. In addition, a unified approach should describe the deconfinement and chiral symmetry restoring phase transition exhibited by strongly-interacting matter under extreme conditions of temperature and density. Nonperturbative Dyson...

Properties and temperature behavior of π and σ bound states are studied in the framework of the nonlocal model with a separable interaction kernel based on the quark Dyson-Schwinger and the meson Bethe-Salpeter equations. Mπ(T ), fπ(T ), Mσ(T ) and Γσ→ππ(T ) are considered above and below the deconfinement and chiral restoration transitions.

Glueball enhancement by color deconfinement

Quantum chromodynamics (QCD) is the theory of the strong interactions [1]. At low temperatures its elementary constituents are mesons, baryons and glueballs [2], this is the hadronic phase where all states are color singlets. At very high temperatures one expects a phase transition, called deconfinement, to take place. The new phase was thought to be a plasma of quarks and gluons and was named ...
