“…With the standard Woods-Saxon nuclear density [20], the Glauber-Gribov approach can successfully consider the b-dependence effect [21,22]. For a heavy target, the projectile partons will also undergo multiple scattering in a medium before the prompt photon production [23]. This is called the initial energy loss effect.…”

The nuclear modification factor for prompt photon production in proton-nucleus (p+A) collisions are investigated within the color dipole formalism. By means of the Glauber-Gribov approach, the nuclear effects are studied in various rapidity bins with the evolution equation based saturation models and the phenomenological dipole models. The theoretical results are compared with the experimental data provided by PHENIX, ATLAS and CMS Collaborations. At forward rapidity and midrapidity, a reasonable agreement with the experimental data is shown for the theoretical results with the modified Kharzeev, Levin and Nardi (KLN) model, and the Kowalski and Teaney (KT) model. Then, we analyze the influence of the initial state energy loss effect on the nuclear modification factor and find that it is obvious only at backward rapidity together with small $p_{\mathrm{T}}$. Finally, the theoretical results are also compared with those of JETPHOX Monte Carlo program and the predictive results for the LHCb at very forward rapidities are presented.

By means of the nuclear parton distribution studied only with lepton deep-inelastic scattering experimental data, the J/Ψ “normal nuclear absorption" and energy loss effects are studied in a Glauber formalism at HERA and RHIC energies. Assuming that the absorption cross section σabs increases with the charmonium-nucleon center of mass energy, the results reveal a significant dependence of the σabs on rapidity y at RHIC energies. The initial-state energy loss effect, which is found important only at HERA energies, is also considered, and its influence should be eliminated when we studied the absorption effect at low collision energies. Finally, we also present the theoretical prediction for LHC.
