abstract="The cross-sections of exclusive (coherent) photoproduction J/psi and (2S) mesons in ultra-peripheral PbPb collisions at a nucleon-nucleon centre-of-mass energy of 5.02TeV are measured using a data sample corresponding to an integrated luminosity of 228 +/- 10 $\mu$b(-1), collected by the LHCb experiment in 2018. The differential cross-sections are measured separately as a function of transverse momentum and rapidity in the nucleus-nucleus centre-of-mass frame for J/psi and psi(2S) mesons. The integrated cross-sections are measured to be sigma(coh)(J/psi) = 5.965 +/- 0.059 +/- 0.232 +/- 0.262mb and sigma(coh)(psi(2S)) = 0.923 +/- 0.086 +/- 0.028 +/- 0.040mb, where the first listed uncertainty is statistical, the second systematic and the third due to the luminosity determination. The cross-section ratio is measured to be sigma(coh)(psi(2S)) /sigma(coh)(J/psi) = 0.155 +/- 0.014 +/- 0.003, where the first uncertainty is statistical and the second is systematic. These results are compatible with theoretical predictions.",
