## Abstract

In this talk, I start with a brief introduction to Non-Relativistic QCD (NRQCD) and its applications to quarkonium physics. This theory has provided a consistent framework for the physics of quarkonia, in particular, the colour-octet Fock components predicted by NRQCD have important implications for the phenomenology of charmonium production in experiments. We discuss the applications of NRQCD to $J/\\psi$ production at Tevatron and the tests of the theory in other experiments. Finally we discuss the production of the ${}^1P\_1$ charmonium state, $h\_c$, at large-$p\_T$ at the Tevatron. The observation of $h\_c$ is interesting, since its existence has yet to be experimentally confirmed. Moreover, this rate is a $prediction$ of NRQCD, and the observation of the $h\_c$ at the Tevatron can, therefore, be used as a test of NRQCD.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
