In this article, the angular correlation between pions and photons produced in deuteron-gold collisions at RHIC and proton-lead collisions at LHC using the color glass condensate formalism was investigated.Abstract:
We investigate the angular correlation between pions and photons produced in deuteron–gold collisions at RHIC and proton–lead collisions at LHC using the color glass condensate formalism. We make predictions for the dependence of the production cross section on the angle between the pion and the photon at different rapidities and transverse momenta. Measuring this dependence would shed further light on the role of the high gluon-density effects and saturation dynamics at RHIC and LHC.read more

TL;DR: A review of applications of the Color Glass Condensate to the phenomenology of relativistic heavy ion collisions can be found in this article, where the initial stages of the collision can be understood in terms of the nonperturbatively strong nonlinear glasma color fields.

TL;DR: In this paper, the authors compute the differential cross-section for photon+quark production in deeply inelastic scattering of electrons off nuclei at small x (e + A DIS) in the framework of the Color Glass Condensate effective field theory, expressing as a convolution of the leading order (in the strong coupling αs) impact factor for the process and universal dipole matrix elements, in the limit of hard photon transverse momentum relative to the nuclear saturation scale.

Prompt photon-jet angular correlations at central rapidities in p +A collisions
TL;DR: In this article, the transverse-momentum-dependent gluon distribution of the nucleus in the regime of nonlinear color fields was derived from photon-jet azimuthal correlations in proton-nucleus collisions.

Quarks at next-to-eikonal accuracy in the CGC I: Forward quark-nucleus scattering
TL;DR: This article derived next-to-eikonal (NEik) corrections to the background quark propagator, which stem from (i) considering a finite longitudinal width target instead of an infinitely thin shockwave and (ii) including the interaction of the quark with the transverse components of the background field.

Cronin effect and high p(T) suppression in pA collisions
TL;DR: In this article, the predictions of the theory of a color glass condensate for a gluon production cross section in $p(d)A$ collisions are reviewed. But they do not consider the effect of quantum evolution at higher energies or rapidities.

Forward inclusive dijet production and azimuthal correlations in pA collisions
TL;DR: In this article, the authors derived forward inclusive dijet production in the scattering of a dilute hadron off an arbitrary dense target, whose partons with small fraction of momentum x are described by a color glass condensate.

TL;DR: For the resulting spectrum of produced gluons in p-A and A-A collisions, the nonlinear QCD evolution is unable to generate a Cronin-type enhancement, and it quickly erases any such enhancement which may be present at lower energies.

Forward quark jets from protons shattering the color glass condensate.
TL;DR: The single-inclusive minijet cross section in pA at forward rapidity within the color glass condensate model of high energy collisions is considered and it is shown that the nucleus appears black to the incident quarks except for very large impact parameters.
