## Abstract

Non-Relativistic QCD (NRQCD) has provided a consistent framework for the physics of quarkonia. The colour-octet Fock components predicted by NRQCD have important implications for the phenomenology of quarkonium production in experiments. We have considered the consequences of the colour-octet channels for the production of the $^1P\_1$ charmonium state, $h\_c$, at large-p\_T at the Tevatron. The colour-octet contributions to this state are found to be dominant and give a reasonably large rate for the production of $h\_c$. This should make it feasible to look for this resonance in the $J/\\psi +\\pi$ decay channel. The observation of $h\_c$ is interesting in its own right, 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.
