After an introduction motivating the study of quarkonium production, we review the recent
developments in the phenomenology of quarkonium production in inclusive scatterings of …

▪ Abstract Recent data from the Tevatron collider have revealed that the production rate of
prompt charmonium at large transverse momentum is orders of magnitude larger than the …

We present a calculation of next-to-leading order (NLO) QCD corrections to total hadronic
production cross sections and to light-hadron-decay rates of heavy quarkonium states. Both …

The theoretical description of heavy quarkonium production at high-energy pp and ep
colliders is reviewed. Predictions based on non-relativistic QCD factorisation are confronted …

This report is the result of the collaboration and research effort of the Quarkonium Working
Group over the last three years. It provides a comprehensive overview of the state of the art …

Results on J/ψ production in ep interactions in the H1 experiment at HERA are presented.
The J/ψ mesons are produced by almost real photons (Q2≈ 0) and detected via their …

We calculate the next-to-leading-order QCD corrections to J/ψ polarization at the Fermilab
Tevatron and CERN Large Hadron Collider. Our results show that the J/ψ polarization status …

We discuss heavy quarkonium production through parton fragmentation, including a review
of arguments for the factorization of high-p T particles into fragmentation functions for …

We analyze charmonium and bottomonium production at fixed-target experiments. We find
that the inclusion of color octet production channels removes large discrepancies between …

The Next-To-Leading-Order (NLO) QCD corrections to J/ψ production via S-wave color-octet
states at the Tevatron and LHC are calculated. There are only slight changes to the …
