TL;DR: In this paper, a general transport equation is proposed which includes energy spreading effects, and a number of specific kinetic equations which are the non-equilibrium versions of well-known many-body theories for equilibrated nuclear matter are discussed.

TL;DR: In this article, the ground-state energy of a quark gas up to and including effecs of fourth order in the quark-gluon coupling was calculated in terms of a chemical-potential-dependent coupling.
Abstract: We calculate the ground-state energy of a quark gas up to and including effecs of fourth order in the quark-gluon coupling. Renormalization-group techniques are used to rewrite the results of the fourth-order calculation in terms of a chemical-potential-dependent coupling. The chemical-potential-dependent coupling approaches zero at high densities. We argue that at hadronic matter densities a phase transition between quark matter and hadronic matter occurs. We show the existence of this phase transition for a three-color, one-flavor quark gas. We find a close correspondence between the results of quantum chromodynamics at large coupling with no bag constant and quantum chromodynamics at small coupling with a bag constant.

TL;DR: In this article, the authors review the physics of nuclear matter at high energy density and the experimental search for the Quark-Gluon Plasma at the Relativistic Heavy Ion Collider (RHIC) and provide several lines of evidence that a novel state of matter has been created in the most violent head-on collisions of Au nuclei at √ s = 200 GeV.

TL;DR: In this article, Cook, McMillan, Peterson, and Sewell showed that the cross sections of nuclei for neutrons of about 90 Mev indicate that the nuclei are partially transparent to high energy neutrons.
Abstract: The experiments of Cook, McMillan, Peterson , and Sewell on the cross sections of nuclei for neutrons of about 90 Mev indicate that the nuclei are partially transparent to high energy neutrons. It is shown that the results can be explained quite satisfactorily using a nuclear radius R=1.37Ai X 10-" cm, a potential energy for the neutron in the nucleus of 31 Mev, and a mean free path for the neutron in nuclear matter of 4.5X 10-" cm. This mean free path agrees with that estimated from the high energy n-p cross section , but the results are not sensitive to the choice of mean free path.

TL;DR: In this article, the quenching of Gamow-Teller matrix elements in light nuclei can be effectively described by a mechanism that governs the $p$-wave pion-nucleus scattering.
Abstract: We propose that the quenching of Gamow-Teller matrix elements in light nuclei can be effectively described by a mechanism that governs the $p$-wave pion-nucleus scattering. This may be providing a solution to the long-standing problem. The resulting Landau-Migdal parameter ${g}^{\ensuremath{'}}$ turns out to be quite consistent with the values extracted from the spectra of pionlike excitations and places a stringent constraint on pion condensation in nuclear matter.
