A Review of Recent Results on Quarkonium Production at LHCb

A selection of LHCb results is presented on the production of heavy quarkonium states in pp collisions, including results on J/ψ and ϓ production at √s = 8 TeV, the measurement of prompt J/ψ polarisation, the production of χc mesons from converted photons, exclusive charmonium production, double J/ψ production, as well as recent results on J/ψ production in proton-lead collisions at √sNN = 5 TeV
