TL;DR: In this article, the early stages of heavy ion collisions at high energy in the Color Glass Condensate framework are described, from the pre-collision high energy nuclear wave function to the point where hydrodynamics may start becoming applicable.
Abstract: In this review, I present the description of the early stages of heavy ion collisions at high energy in the Color Glass Condensate framework, from the pre-collision high energy nuclear wave function to the point where hydrodynamics may start becoming applicable.

TL;DR: In this paper, the leading order (LO) q g → q γ and next-to-leading order (NLO) g g →q q ¯ γ contributions to inclusive photon production in proton-proton (p+p) collisions at the LHC were investigated.

TL;DR: In this paper, the Pomeron loop effects in the evolution equations for the Color Glass Condensate were studied for particle production in asymmetric, "dilute-dense" collisions, where a dilute projectile scatters off a dense target whose gluon distribution is highly evolved.

TL;DR: In this paper, the effects of linearly polarized gluons inside unpolarized hadrons and unpolarised hadrons inside transversely polarized hadrons were explored for the linearized gluon TMDs.
Abstract: Quarkonium production offers good possibilities to study gluon TMDs. In this proceedings contribution this topic is explored for the linearly polarized gluons inside unpolarized hadrons and unpolarized gluons inside transversely polarized hadrons. It is argued that $$\chi _{b0/2}$$
and $$\eta _b$$
production at LHC are best to study the effects of linearly polarized gluons in hadronic collisions, by means of angular independent ratios of ratios of cross sections. This can be directly compared to $$\cos 2\phi $$
asymmetries in heavy quark pair and dijet production in DIS at a future high-energy Electron-Ion Collider (EIC), which probe the same TMDs. In the small-x limit this corresponds to the Weizsacker–Williams (WW) gluon distributions, which should show a change in behavior for transverse momenta around the saturation scale. Together with investigations of the dipole (DP) gluon distributions, this can provide valuable information about the polarization of the Color Glass Condensate if sufficiently small x-values are reached. Quarkonia can also be useful in the study of single transverse spin asymmetries. For transversely polarized hadrons the gluon distribution can be asymmetric, which is referred to as the Sivers effect. It leads to single spin asymmetries in for instance $$J{/}\psi $$
(pair) production at AFTER@LHC, which probe the WW or f-type gluon Sivers TMD. It allows for a test of a sign-change relation w.r.t. the gluon Sivers TMD probed at an EIC in open heavy quark pair production. Single spin asymmetries in backward inclusive C-odd quarkonium production, such as $$J{/}\psi $$
production, may offer probes of the DP or d-type gluon Sivers TMD at small x-values in the polarized proton, which in that limit corresponds to a correlator of a single Wilson loop, describing the spin-dependent odderon.

TL;DR: In this paper, the authors studied the SU(2) 3+1-D Yang-Mills equations for matter produced in a high-energy heavy-ion collision and showed that the growth of the amplitude of fluctuations is due to a non-Abelian Weibel instability, the scale of which is set by dynamically generated plasmon mass.
Abstract: Based on our work hep-ph/0510121, we discuss further the numerical study of classical SU(2) 3+1-D Yang-Mills equations for matter produced in a high-energy heavy-ion collision. The growth of the amplitude of fluctuations as exp(Γ\( \sqrt{{g^2\mu\tau}}\)) (where g2μ is a scale arising from the saturation of gluons in the nuclear wave function) is shown to be robust over a wide range of initial amplitudes that violate boost invariance. We argue that this growth is due to a non-Abelian Weibel instability, the scale of which is set by a dynamically generated plasmon mass. We discuss the relation of Γ to the prediction from kinetic theory.
