متن کاملSuppression of Quarkonium Production in Heavy Ion Collisions at RHIC and LHC
A model for the production of quarkonium states in the midrapidity region at RHIC and LHC energy range is presented which explores well understood properties of QCD only. An increase of the quarkonium hadronisation time with the initial energy leads to a gradual change of the most important phenomena from fixed targetto collider-energies. We evaluate nuclear effects in the quarkonium production...
متن کاملGluon fragmentation into heavy quarkonium.
The dominant production mechanism for heavy quark-antiquark bound states in very high energy processes is fragmentation, the splitting of a high energy parton into a quarkonium state and other partons. We show that the fragmentation functions D(z, μ) describing these processes can be calculated using perturbative QCD. We calculate the fragmentation functions for a gluon to split into S-wave qua...
متن کاملRecent Progress in the Theory of Heavy Quark and Quarkonium Production in Hadronic Collisions
We review heavy quark and quarkonium production in high energy hadronic collisions. We discuss the status of the theoretical calculations and their uncertainties. We then compare the current theoretical results with the most recent measurements from the Tevatron Collider experiments Heavy quark production in high energy hadronic collisions consitutes a benchmark process for the study of perturb...
متن کاملInclusive Heavy-quarkonium Production in Hadronic Collisions∗
We discuss the theory of inclusive production of heavy quarkonium, the comparison between theory and experiment, and the expected nuclear effects in cold nuclear targets. We also present predictions, based on Nonrelativistic QCD (NRQCD), for quarkonium production cross sections in the LHC energy range. We find that nuclear effects in the production cross sections are largely independent of the ...
