TL;DR: In this article, the incoherent elastic scattering of partons, as present in a multi-phase transport model (AMPT), with a modest parton-parton cross-section of sigma = 1.5-3 mb, naturally explains the long-range two-particle azimuthal correlation as observed in proton-proton and protonnucleus collisions at the Large Hadron Collider.

TL;DR: In this article, the azimuthal correlation between a forward � 0 and an associated particle at large rapidity is shown to be sensitive to the low-x gluon density.

TL;DR: The color glass condensate as discussed by the authors is a state of high-density gluonic matter which controls the high-energy limit of hadronic matter, and it has been applied to the description of ultrarelativistic nuclear collisions.
Abstract: The Color Glass Condensate is a state of high-density gluonic matter which controls the high-energy limit of hadronic matter. The article begins with a discussion of general problems of high-energy strong interactions. The infinitemomentum- frame description of a single hadron at very small x is developed, and this picture is applied to the description of ultrarelativistic nuclear collisions. Recent developments in the renormalization group description of the Color Glass Condensate are reviewed.

TL;DR: In this paper, the color glass condensate (CGC) framework was used to study the production of forward heavy quark-antiquark pairs in unpolarized proton-nucleus or protonproton collisions in the small-x regime.
Abstract: We use the color glass condensate (CGC) framework to study the production of forward heavy quark-antiquark pairs in unpolarized proton-nucleus or proton-proton collisions in the small-x regime. In the limit of nearly back-to-back jets, the CGC result simplifies into the transverse-momentum dependent (TMD) factorization approach. For massless quarks, the TMD factorization formula involves three unpolarized gluon TMDs: the Weizsacker-Williams gluon distribution, the adjoint-dipole gluon distribution, and an additional one. When quark masses are kept nonzero, three new gluon TMDs appear—each partnered to one of the aforementioned distributions—which describe the distribution of linearly polarized gluons in the unpolarized small-x target. We show how these six gluon TMDs emerge from the CGC formulation, and we determine their expressions in terms of Wilson line correlators. We calculate them analytically in the McLerran-Venugopalan model, and further evolve them toward smaller values of x using a numerical implementation of Jalilian-Marian-Iancu-McLerran-Weigert-Leonidov-Kovner (JIMWLK) evolution.
