TLDR
In this paper, the effect of gluon saturation in the wave functions of colliding nuclei was investigated. And the authors showed that the dominant production mechanism in proton-nucleus and nucleus nucleus collisions for heavy nuclei is different from the one in hadron-hadron interactions.About:

Heavy Quarks in the Quark-Gluon Plasma
Ralf Rapp,Hendrik van Hees +1 more
TL;DR: In this article, the authors review recent progress in understanding of the interactions of charm and bottom quarks in the Quark-Gluon Plasma (QGP), focusing on elastic interactions for which the large quark mass enables a Brownian motion treatment.

ϒ production as a probe for early state dynamics in high energy nuclear collisions at RHIC
TL;DR: In this article, the authors investigated the production of heavy ion collisions at RHIC energy and showed that the excited b b ¯ states are characterized by the competition between the cold and hot nuclear matter effects and sensitive to the dissociation temperatures determined by the heavy quark potential.

Color Deconfinement and Charmonium Production in Nuclear Collisions
Louis Kluberg,Helmut Satz +1 more
TL;DR: In statistical QCD, color deconfinement and the properties of the quark-gluon plasma determine the in-medium behavior of heavy quark bound states as discussed by the authors.

Quarkonium production in high energy proton-nucleus collisions: CGC meets NRQCD
TL;DR: In this article, the production of heavy quarkonium states in high energy proton-nucleus collisions was studied under the color glass condensate (CGC) framework, and expressions in the Non-Relativistic QCD (NRQCD) factorization formalism for heavy quarksonium differential cross sections as a function of transverse momentum and rapidity were obtained.

$J/\psi$ Suppression by Quark-Gluon Plasma Formation
T Matsui,Helmut Satz,Helmut Satz +2 more
TL;DR: In this paper, the temperature dependence of the screening radius, as obtained from lattice QCD, is compared with the J/ψ radius calculated in charmomium models, and the feasibility to detect this effect clearly in the dilepton mass spectrum is examined.

Exclusive Processes in Perturbative Quantum Chromodynamics
TL;DR: In this article, a systematic analysis in perturbative quantum chromodynamics (QCD) of large-momentum-transfer exclusive processes is presented, where the scaling behavior, angular dependence, helicity structure, and normalization of elastic and inelastic form factors and large-angle exclusive scattering amplitudes for hadrons and photons are given.
Journal ArticleDOI
Semihard processes in QCD
TL;DR: In this article, the effects of parton-parton interactions (screenings), that stop the increase of the cross sections near their unitarity limit, and the coherent emission of soft gluons by the global colour charge of whole groups of harder particles, are studied in detail.

Computing quark and gluon distribution functions for very large nuclei.
Larry McLerran,Raju Venugopalan +1 more
TL;DR: It is argued that the distribution functions for quarks and gluons are computable at small {ital x} for sufficiently large nuclei, perhaps larger than can be physically realized, and that weak coupling methods may be used.

Gluon distribution functions for very large nuclei at small transverse momentum.
Larry McLerran,Raju Venugopalan +1 more
TL;DR: It is shown that the gluon distribution function for very large nuclei may be computed for small transverse momentum as correlation functions of an ultraviolet finite two-dimensional Euclidean field theory.
