Measurements are presented of the cross-section for the central exclusive production of J/\psi\to\mu^+\mu^- and \psi(2S)\to\mu^+\mu^- processes in proton-proton collisions at \sqrt{s} = 13 TeV with 2016-2018 data. They are performed by requiring both muons to be in the LHCb acceptance (with pseudorapidity 2<\eta_{\mu^\pm} < 4.5) and mesons in the... Show more
