# Systematics of quarkonium production at the LHC and double parton fragmentation

@article{Fleming2012SystematicsOQ, title={Systematics of quarkonium production at the LHC and double parton fragmentation}, author={Sean P Fleming and Adam K. Leibovich and Thomas Mehen and Ira Z. Rothstein}, journal={Physical Review D}, year={2012}, volume={86}, pages={094012} }

In this paper we discuss the systematics of quarkonium production at the LHC. In particular, we focus on the necessity to sum logs of the form log(Q/p⊥) and log(p⊥/mQ). We show that the former contributions are power suppressed, while the latter, whose contribution in fragmentation is well known, also arise in the short distance (i.e., non-fragmentation) production mechanisms. Though these contributions are suppressed by powers of mQ/p⊥, they can be enhanced by inverse powers of v, the relative…
