Abstract
The exclusive coherent quarkonia photo-production in (ultra-)peripheral collisions is sensitive to the partonic structure of nuclei, to the choice of the vector meson wave function and to the profile of coherence of the interactions. LHCb has a good capability to measure coherent $J/\psi$ and $\psi(2S)$ photo-production in (ultra-)peripheral PbPb collisions at a nucleon-nucleon centre-of-mass energy of 5.02 TeV at the forward rapidity region. In this document, we will present the measurement of coherent $J/\psi$ and $\psi(2S)$ photo-production in ultra-peripheral PbPb collisions and coherent $J/\psi$ photo-production in peripheral PbPb collisions at LHCb, as well as the respective comparison with the latest theoretical predictions. Prospects for future quarkonia photo-production measurements at LHCb will be discussed.
