Description

In quasi-elastic proton-proton collisions at the LHC, central exclusive production (CEP) of vector mesons can take place via the fusion of a photon and a pomeron (a colourless strongly-coupled object with the quantum numbers of the vacuum), while the protons remain intact. The central exclusive production of $J/\psi$ and $\psi$(2S) mesons provides clean events, which is uncommon at hadron colliders. This presentation shows results for CEP production of $J/\psi$ and $\psi$(2S) mesons at LHCb, both in $pp$ collisions at a centre of mass energy, $\sqrt{s}$, of 13 TeV and in PbPb collisions at $\sqrt{s_{NN}}=5$ TeV.
