TL;DR: In this paper, the form factors on the charm meson vertices are determined from QCD sum rules calculations. But these form factors became available only very recently, and the last one, needed for our present purpose, is calculated in this work.

TL;DR: In this paper, the authors used the Kharzeev-Levin-Nardi (KLN) model of the low x gluon distributions to fit recent HERA data on F{sub L} and F {sub 2}{sup c} (F{sub 2{sup b}).

Abstract: At very high energies we expect that the hadronic cross sections satisfy the Froissart bound, which is a well-established property of the strong interactions. In this energy regime we also expect the formation of the Color Glass Condensate, characterized by gluon saturation and a typical momentum scale: the saturation scale Qs. In this paper we show that if a saturation window exists between the nonperturbative and perturbative regimes of Quantum Chromodynamics (QCD), the total cross sections satisfy the Froissart bound. Furthermore, we show that our approach allows us to describe the high energy experimental data on $pp/p\bar p$ total cross sections.

TL;DR: In this article, the authors considered the color glass condensate formalism and showed that at large energies the coherence of the projectile quarks is lost and that the leading baryon production mechanism changes from recombination to independent fragmentation.

TL;DR: The Interacting Gluon Model (IGM) as discussed by the authors is a tool designed to study energy flow, especially stopping and leading particle spectra, in high energy hadronic collisions.
