TL;DR: In this article, the energy and rapidity dependence of the average transverse momentum pT in pp and pA collisions at RHIC and LHC energies in the framework of the Color Glass Condensate (CGC) formalism was computed.
Abstract: We compute the energy and rapidity dependence of the average transverse momentum pT in pp and pA collisions at RHIC and LHC energies in the framework of the Color Glass Condensate (CGC) formalism. We update previous predictions for the pT - spectra using the hybrid formalism of the CGC approach and two phenomenological models for the dipole – target scattering amplitude. We demonstrate that these models are able to describe the RHIC and LHC data for the hadron production in pp, dAu and pPb collisions at pT ≤ 20 GeV. Moreover, we present our predictions for pT and demonstrate that the ratio pT (y)=pT (y = 0) decreases with the rapidity and has a behavior similar to that predicted by hydrodynamical calculations.

TL;DR: In this article , the authors investigated the D -meson production by considering the unintegrated gluon distribution within the dipole approach in the momentum representation and compared the results with the Glauber-Gribov framework.
Abstract: Abstract The D -meson production is investigated by considering the unintegrated gluon distribution within the dipole approach in the momentum representation. We analyze the D -meson spectrum accounting for the effects of nonlinear behavior of the QCD dynamics which can be accordingly addressed in the dipole framework. The unintegrated gluon distribution is obtained by using geometric scaling property and the results are compared to the Glauber–Gribov framework. The absolute transverse momentum spectra and the nuclear modification ratios are investigated. Predictions are compared with the experimental measurements by the ALICE and LHCb Collaborations in pA collisions for different rapidity bins.

TL;DR: In this article, the authors calculate differential energy spectra of charmed particles produced in proton-nucleus collisions, assuming the existence of intrinsic heavy quark components in the proton wave function.
Abstract: We calculate differential energy spectra ($x_F$-distributions) of charmed particles produced in proton-nucleus collisions, assuming the existence of intrinsic heavy quark components in the proton wave function. For the calculation, the recently proposed factorization scheme is used, based on the Color Glass Condensate theory and specially suited for predictions of a production of particles with large rapidities. It is argued that the intrinsic charm component can, if it exists, dominate in a sum of two components, intrinsic + extrinsic, of the inclusive spectrum of charmed particles produced in proton-nucleus collisions at high energies, in the region of medium $x_F$, $0.15 < x_F < 0.7$, and can give noticeable contribution to atmospheric fluxes of prompt muons and neutrinos.

TL;DR: In this paper, the nuclear modification factor derived from the inclusive yields of π0 mesons in p+p and d+Au collisions at center of mass energy sNN = 200 GeV and pseudorapidity = 4.00 (d beam direction) were reported.
Abstract: Measurements of the inclusive yields of π0 mesons in p+p and d+Au collisions at center of mass energy sNN = 200 GeV and pseudorapidity 〈η〉 = 4.00 (d beam direction) are reported. The yield for p+p collisions is in general agreement with perturbative QCD calculations. The d+Au yield is in agreement with a calculation which models the Au nucleus as a Color Glass Condensate for forward particle production. The nuclear modification factor derived from the inclusive yields is qualitatively consistent with models which suppress the gluon density in nuclei.
