Description
Charmonium production measurements are powerful tests of QCD. The models of charmonium production separate the quark pair production, well understood, and the hadronisation, which is non perturbative. The most successful model so far, non-relativistic QCD, requires input from experimental results to constrain the non-perturbative component. With its precise vertex reconstruction, powerful charged hadron identification and a flexible trigger, the LHCb experiment at the LHC is well-suited for charmonium measurements. In this talk, a summary of recent charmonium(-like) states production measurements will be given, including prompt and non-prompt measurement, associated production and production in $p Pb$ collisions.
