Measurement of quarkonium production with CMS

Quarkonium hadroproduction is not satisfactorily understood. Measurements performed at the unprecedented LHC energies, and benefiting from large yields and extended kinematic reach, are anticipated to facilitate crucial improvements to the current understanding. This article presents the initial LHC quarkonium results, based on the data collected by the CMS experiment in the first year LHC pp and PbPb runs.
