TLDR
In this paper, the authors discuss the production of charmed mesons and p(d)A collisions at high energies and argue that when the saturation scale Qs characterizing the parton density in a nucleus exceeds the quark mass m, the naive perturbation theory breaks down.Citations

A density functional study of atomic oxygen and carbon adsorptions on (100) surface of γ-Uranium
Pratik P. Dholabhai,Asok K. Ray +1 more
TL;DR: In this paper, the generalized gradient approximation of the density functional theory (GGA-DFT) with Perdew and Wang (PW) functionals was used for oxygen and carbon adsorption on a?-Uranium (U) (100) surface.

Heavy quark production in Color Glass Condensate
TL;DR: In this article, heavy quark production in High Parton Density QCD in quasi-classical approximation and including low-$x$ quantum evolution is discussed, and an alternative approach based on the effect of pair production in external fields is considered.

Heavy quark production in colour glass condensate
TL;DR: In this paper, heavy quark production in high parton density QCD in quasi-classical approximation and including low-x quantum evolution is discussed and an alternative approach based on the effect of pair production in external fields is considered.

Theoretical summary: The First International Conference on Hard and Electromagnetic Probes in Relativistic Nuclear Collisions
TL;DR: In this article, the authors summarize the theoretical results from the First International Conference "Hard Probes '04", dedicated to the study of the properties of quark-gluon matter and its diagnostics with the hard processes.

On gauge invariance and vacuum polarization
TL;DR: In this paper, it was shown that the extraction of gauge invariants from a formally gauge invariant theory is ensured if one employs methods of solution that involve only gauge covariant quantities.
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.

Operator expansion for high-energy scattering
Ian Balitsky,Ian Balitsky +1 more
TL;DR: In this article, the leading logarithms for high-energy scattering can be obtained as a result of evolution of the non-local operators (straight-line ordered gauge factors) with respect to the slope of the straight line.

Small-x F 2 structure function of a nucleus including multiple Pomeron exchanges
TL;DR: In this paper, the authors derived an equation determining the small-x evolution of the F{sub 2} structure function of a large nucleus which includes all multiple Pomeron exchanges in the leading logarithmic approximation using Mueller{close_quote}s dipole model.
