TL;DR: In this paper, the authors investigate how thermalization of gluons depends on the initial conditions assumed in ultrarelativistic heavy-ion collisions at RHIC, and they find that full kinetic equilibrium is achieved slightly sooner in denser systems and its timescale tends to saturate.
Abstract: We investigate how thermalization of gluons depends on the initial conditions assumed in ultrarelativistic heavy-ion collisions at RHIC. The study is based on simulations employing the pQCD inspired parton cascade solving the Boltzmann equation for gluons. We consider independently produced minijets with p
T > p
0 = 1.3-2.0GeV and a color glass condensate as possible initial conditions for the freed gluons. It turns out that full kinetic equilibrium is achieved slightly sooner in denser systems and its timescale tends to saturate. Compared with the kinetic equilibration we find a stronger dependence of chemical equilibration on the initial conditions.

TL;DR: In this paper, a model based on the Color Glass Condensate framework was proposed to predict the modification of quarkonium production between p-p and p-Pb collisions.
Abstract: Gluon saturation effects are expected to occur at small parton momentum fraction Bjorken- x , affecting particle production in heavy ion collisions. In these proceedings, we focus on quarkonium production in the forward rapidity region in p-Pb collisions as a tool to search for saturation effects. We describe a model based on the Color Glass Condensate framework that allows to predict the modification of quarkonium production between p-p and p-Pb collisions. In addition, a model including shadowing, the modification of the parton densities in nuclei relative to the nucleon, will be described. The results from both models are compared. Finally we will discuss some aspects of the detection performance of the ALICE Forward Muon Spectrometer and we will present the perspectives in terms of expected statistics for the forthcoming p-Pb collisions.

TL;DR: In this article, the onset of the quantum regime is derived as a critical stable point in the nuclear configurational entropy, matching the fitted experimental data in the literature with accuracy of 1%.
Abstract: The dipole-nucleus forward scattering amplitude rules the onset of the gluon anomalous dimension, in the Color-Glass Condensate regime. In this model, the onset of quantum regime is here derived as a critical stable point in the nuclear configurational entropy, matching the fitted experimental data in the literature with accuracy of 1%. It corroborates with the informational entropy paradigm in high energy nuclear physics.

TL;DR: In this paper, the McLerran-Venugopalan model was modified to include only a finite number of sources of color charge, and a Coulombic interaction was introduced.
