Central Exclusive Production at LHCb

Central Exclusive Production (CEP) is a unique process at hadron machines in which particles are produced via colourless propagators. LHCb have measured the cross-sections for the CEP of vector mesons, $J/ψ,ψ(2S),Υ(1S),Υ(2S)$ and $Υ(3S)$, which are photo-produced. In the double pomeron exchange process, preliminary measurements have been made of $χ_{c0},χ_{c1}, χ_{c2}$ meson production while the first observations of the CEP of pairs of charmonia, $J/ψJ/ψ$ and $J/ψψ(2S)$, have been made and limits obtained on the pair production of other charmonia.
