TL;DR: In this paper, Borel-transformed QCD sum rules are used to describe an interaction between the D-meson and a nucleon by taking into account all the lowest dimension-4 operators in the operator product expansion (OPE).

TL;DR: In this paper, the authors investigated the compression of nuclear matter in relativistic hydrodynamics and provided a solution to the "slab-on-slab" collision problem over a range of incident velocities.

TL;DR: In this paper, the relativistic Hartree equations for spherical nuclei have been derived from a quark model of the structure of bound nucleons which interact through the exchange of scalar (σ) and vector (ω and ϱ) mesons.

TL;DR: In this article, the collisional damping time is comparable to the duration of the collision for medium-weight nuclei and it is shown that the predictions of mean field theory, such as the presence of a fusion window at small impact parameters, will only have validity for lighter ions.
Abstract: The collision rate in an infinite Fermi system having a deformed Fermi surface is computed in the limit of small deformation. For a given amount of internal energy, the damping rate is nearly independent of temperature. The calculation is applied to thermalization in heavy ion collisions. We find that the collisional damping time is comparable to the duration of the collision for medium-weight nuclei. Thus the predictions of mean field theory, such as the presence of a fusion window at small impact parameters, will only have validity for lighter ions.

TL;DR: In this article, the effects of nuclear absorption and shadowing on mid-rapidity quarkonium production were investigated in proton-nucleus collisions, and the energy, rapidity, and impact-parameter dependence of shadowing was analyzed.
Abstract: The charmonium yields are expected to be considerably suppressed if a deconfined medium is formed in high-energy heavy-ion collisions. In addition, the bottomonium states, with the possible exception of the UPSILON(1S) state, are also expected to be suppressed in heavy-ion collisions. However, in proton-nucleus collisions the quarkonium production cross sections, even those of the UPSILON(1S), are also suppressed. These 'cold nuclear matter' effects need to be accounted for before signals of the high-density QCD medium can be identified in the measurements made in nucleus-nucleus collisions. We identify two cold nuclear matter effects important for midrapidity quarkonium production: 'nuclear absorption', typically characterized as a final-state effect on the produced quarkonium state, and 'shadowing', the modification of the parton densities in nuclei relative to the nucleon, an initial-state effect. In this article, we characterize these effects and study the energy, rapidity, and impact-parameter dependence of initial-state shadowing.
