Review of quarkonium production: status and prospects

Understand

Production cross sections of heavy quarkonia are considered as useful tools to study various aspects of QCD.

• We have entered a new era of quarkonium production phenomenology, with the help of new measurements from the LHC giving access to more varieties of observables, and recent theoretical developments that provided us a better understanding of the short-distance process in which quarkonia are produced.
• With a more concrete understanding of perturbative corrections and a prolific collection of data, a satisfactory description of the quarkonium production mechanism might now be within reach.
• Unfortunately, the exact mechanism of quarkonium production still remains elusive.
