Investigation of diffractive photoproduction of $J/\Psi$ in hadronic collisions

Understand

In this work we study the diffractive photoproduction of $J/\Psi$ in proton-proton, proton - nucleus and nucleus - nucleus collisions at LHC energies using the color dipole formalism and different models for the forward dipole - target scattering amplitude.

• Our goal is to estimate the theoretical uncertainty present in the current predictions in the literature.
• Our results are compared with the experimental data and predictions for higher energies are presented.
