Description
Understanding charmonium production in hadron collisions is an important challenge to QCD. A rewiew will be presented of the existing theoretical models, with a focus on recent developments of calculations at NLO in nonrelativistic QCD and global fits to long-distance matrix elements. Measurements at the LHC, and in particular with the data collected by the CMS experiment in 2010-2011, will be discussed, highlighting the experimental techniques and data analysis strategies. These measurements include prompt and non-prompt charmonium cross-sections, bottomonium cross-sections, production of P-wave states and exotic charmonia.
