  Vector meson production in ultra-peripheral pA and AA collisions at the CERN
Large Hadron Collider (LHC) are very sensitive to Parton Distribution Functions
(PDF) as well as to their leading-order, next-to-leading-order, and medium
corrections. This process is a complimentary tool to explore the effects of
different PDFs in particle production in proton-nucleus and nucleus-nucleus
central collisions. Existing and forthcoming data available, e.g., from ALICE
and CMS, may be used in conjunction with our theoretical predictions to
constrain the PDFs. We make predictions for rapidity distributions and for
cross sections of J/$\psi$ , $\psi(2S)$ and $\Upsilon$ production at
$\sqrt{s_{NN}}=2.76$ TeV and $\sqrt{s_{NN}}=5$ TeV. We use the second energy as
representative for the Run 2 of PbPb collisions at the LHC.
