We argue that although at asymptotically high temperatures the QGP in bulk behaves as a gas of weakly interacting quasiparticles (modulo long-range magnetism), at temperatures up to few times the critical temperature $T_c$ it displays different properties. If the running of the QCD coupling constant continues in the Coulomb phase till the screening length scale, it reaches the strong coupling treshold $\alpha_s(m_D)\sim 1$. As a result, the Coulomb phase supports weakly bound Coulombic s-wave… Expand

Matter formed at the BNL Relativistic Heavy Ion Collider.
TLDR
It is suggested that the "new form of matter" found just above T(c) by the Relativistic Heavy Ion Collider is made up of tightly bound quark-antiquark pairs, essentially 32 chirally restored mesons of the quantum numbers of pi, sigma, rho, and a1. Expand

Chemical equilibration in relativistic heavy ion collisions

TLDR
It is conjectured here that the characterization of the plasma as a free or weakly interacting gas of quarks and gluons is valid only for short distances and short time scales of the order 1/T, but that at scales larger than 1/g/sup 2/T the plasma exhibits confining features similar to that of the low-temperature hadronic phase.

Understanding the strong coupling limit of the N=4 supersymmetric Yang-Mills theory at finite temperature
Recently, a number of intriguing results have been obtained for strongly coupled ${\cal N}=4$ Supersymmetric Yang-Mills theory in vacuum and matter, using the AdS/CFT correspondence. In this work, weExpand
Erratum: Propagation of quarks in the spatial direction in hot QCD
TLDR
The results do not contradict the idea that the normal electric interaction of color charges is screened and produces no bound states in the usual sense and the transition from three- to two-dimensional positronium is discussed in detail including relativistic effects. Expand

J/psi and eta(c) in the deconfined plasma from lattice QCD.
TLDR
Analyzing correlation functions of charmonia at finite temperature (T) on 32(3)x(32-96) anisotropic lattices by the maximum entropy method (MEM) finds that J/psi and eta(c) survive as distinct resonances in the plasma even up to T approximately 1.6T(c), which suggests that the deconfined plasma is nonperturbative enough to hold heavy-quark bound states.
