TL;DR: In this paper, the authors discuss forward-backward correlations in the multiplicity of produced particles in heavy ion collisions and find that the color glass condensate generates distinctive predictions for the long range component of this correlation.

TL;DR: In this article, the authors compute quark-antiquark pair production in the context of the color glass condensate model for central heavy-ion collisions analytically to leading order in the density of hard sources present in the projectiles, and is applicable to quarks with a mass large compared to the saturation momentum.
Abstract: We compute quark-antiquark pair production in the context of the color glass condensate model for central heavy-ion collisions. The calculation is performed analytically to leading order in the density of hard sources present in the projectiles, and is applicable to quarks with a mass large compared to the saturation momentum. The formulas derived in this paper are compared to expressions derived in the framework of collinearly factorized perturbative QCD and in ${k}_{\ensuremath{\perp}}$ factorization models. We comment on the breaking of ${k}_{\ensuremath{\perp}}$ factorization which occurs beyond leading order in our approach.

TL;DR: Two widely proposed k(t)-dependent gluon distributions in the small-x saturation regime are investigated using two-particle back-to-back correlations in high energy scattering processes.
Abstract: Two widely proposed kt-dependent gluon distributions in the small-x saturation regime are investigated using two particle back-to-back correlations in high energy scattering processes. The Weizsacker-Williams gluon distribution, interpreted as the number density of gluon inside the nucleus, is studied in the quark-antiquark jet correlation in deep inelastic scattering. On the other hand, the unintegrated gluon distribution, defined as the Fourier transform of the color-dipole cross section, is probed in the direct photon-jet correlation in pA collisions. Dijet-correlation in pA collisions depends on both gluon distributions through combination and convolution in the large Nc limit. We calculate these processes in two approaches: the transverse momentum dependent factorization approach and the color-dipole/color glass condensate formalism, and they agree with each other completely.

TL;DR: In this paper, an integrated dynamical model composed of a fully (3+1) dimensional ideal hydrodynamic model with a state-of-the-art equation of state based on lattice QCD, and subsequent hadronic cascade in the late stage is presented.

TL;DR: The authors performed the first dipole picture fit to HERA inclusive cross section data using the full next-to-leading order (NLO) impact factor combined with an improved Balitsky-Kovchegov evolution including the dominant effects beyond leading logarithmic accuracy at low $x$.
Abstract: We perform the first dipole picture fit to HERA inclusive cross section data using the full next-to-leading order (NLO) impact factor combined with an improved Balitsky-Kovchegov evolution including the dominant effects beyond leading logarithmic accuracy at low $x$ We find that three different formulations of the evolution equation that have been proposed in the recent literature result in a very similar description of HERA data and robust predictions for future deep inelastic scattering experiments We find evidence pointing toward a significant nonperturbative contribution to the structure function for light quarks, which stresses the need to extend the NLO impact factor calculation to massive quarks
