TL;DR: In this article, the correlation in azimuthal angle between forward dijets in deuteron-gold collisions at RHIC was measured, with both multiple scatterings and non-linear QCD evolution at small-x taken into account.
Abstract: Measuring correlations between forward dijets in deuteron-gold collisions at RHIC will further test the Color Glass Condensate (CGC) picture of the nuclear wavefunction at small-x, which successfully predicted the suppressed production of high-p_T particles at forward rapidities in d+Au collisions: R_dA<1. I present predictions for the correlation in azimuthal angle between forward dijets in the CGC framework, with both multiple scatterings and non-linear QCD evolution at small-x taken into account.

TL;DR: In this article, a 3+1 dimensional Monte Carlo parton cascade including inelastic multiplication processes (gg ggg) is elaborated. But the authors only briefly outline the basic idea of the algorithm.
Abstract: A number of promising results of a new 3+1 dimensional Monte Carlo parton cascade including inelastic multiplication processes (gg ggg) are elaborated: (1) thermalization and chemical saturation; (2) the onset of longitudinal hydrodynamical expansion; (3) the build up of elliptic flow. We first briefly outline the basic idea of the algorithm. Full simulations are done with initial conditions for the kinetic partons via minijets or with ones stemming from a color glass condensate. The inclusion of the inelastic channels leads to a very fast kinetic equilibration and also to an early creation of pressure.

TL;DR: In this article, the authors considered the next-to-leading order (NLO) calculation of single inclusive particle production at forward rapidities in proton-nucleus collisions and in the framework of the Color Glass Condensate (CGC).
Abstract: We consider the next-to-leading order (NLO) calculation of single inclusive particle production at forward rapidities in proton-nucleus collisions and in the framework of the Color Glass Condensate (CGC). We focus on the quark channel and the corrections associated with the impact factor. In the first step of the evolution the kinematics of the emitted gluon is kept exactly (and not in the eikonal approximation), but such a treatment which includes NLO corrections is not explicitly separated from the high energy evolution. Thus, in this newly established "factorization scheme", there is no "rapidity subtraction". The latter suffers from fine tuning issues and eventually leads to an unphysical (negative) cross section. On the contrary, our reorganization of the perturbation theory leads by definition to a well-defined cross section and the numerical evaluation of the NLO correction is shown to have the correct size.

TL;DR: In this article, the authors present the capabilities of the CMS experiment to explore the heavy-ion physics program offered by the CERN Large Hadron Collider (LHC), and the prime goal of this research is to test the fundamental theory of the strong interaction (QCD) in extreme conditions of temperature, density and parton momentum fraction by colliding nuclei at energies of √ s NN = 5.5 TeV.

TL;DR: In this article, the color field of the nuclei within the Color Glass Condensate model was used to calculate the cross-section for the photoproduction of quark-antiquark pairs in the peripheral collision of ultra-relativistic nuclei.
Abstract: In this paper, we calculate the cross-section for the photoproduction of quark-antiquark pairs in the peripheral collision of ultra-relativistic nuclei, by treating the color field of the nuclei within the Color Glass Condensate model. We find that this cross-section is sensitive to the saturation scale Q 2 that characterizes the model. In particular, the transverse momentum spectrum of the produced pairs could be used to measure the properties of the color glass condensate.
