Description
At the LHC, the highly boosted electromagnetic field of the beam
particles represents a source of quasi-real photon. Vector meson
photo-production measurements in pp/Pb-Pb collisions are sensitive to
the gluon parton distribution functions in the proton/nucleus. LHCb
results on charmonium production in ultra-peripheral Pb-Pb collisions at
5.02 TeV and in pp at 13 TeV will be presented.
