On theoretical uncertainty of color dipole phenomenology in the J/Psi   and Upsilon photoproduction in pA and AA collisions at the CERN Large Hadron   Collider
  We investigate the theoretical uncertainty on the predictions for the photoproduction of J/psi and Upsilon states in the proton-nucleus and nucleus-nucleus collisions at the LHC within the color dipole formalism. Predictions for the rapidity distributions are presented and the dependence on the meson wavefunction, heavy quark mass as well as the models for the dipole cross section are analyzed. We compare directly the theoretical results to the recent data from ALICE collaboration on J/psi production in pPb collisions at a centre-of-mass energy per nucleon pair of 5.02 TeV and in PbPb collisions at a centre-of-mass energy per nucleon pair of 2.76 TeV. Predictions are also performed for $\Upsilon$ state in PbPb and pPb and pp collisions at the LHC energies, including the coherent and incoherent contributions.
