Description
We analyze the production of vector mesons ρ and J/Ψ in ultraperipheral proton-nucleus
collisions with center of mass energies √
s = 5, 02 TeV and √
s = 8, 16 TeV. We calculate
the differential cross sections using three phenomenological models that take into account
the effects of parton saturation, and we present predictions for pCa and pP b collisions. We
compare our predictions with the latest data from the CERN-LHC CMS collaboration. We
demonstrate that the models are able to describe the data at small values of t. However,
we observe a suppression compared to the limited available data at large values of t. We
conclude that a future experimental analysis of the region of large t values is necessary
for a more precise comparison between different approaches for the saturation regime.
