Quarkonium Production at ATLAS (15' + 5')
Presented by Kendall REEVES on 9 Jun 2011 from 14:50 to 15:10
Session: 4C Parallel - B, charm and onia
The production of quarkonium is an important testing ground for QCD calculations. The fraction of J/\psi mesons produced from B-hadron decays was measured by the ATLAS experiment and the prompt and non-prompt differential J/\psi production cross-sections determined. The cross-section values extracted from data are compared to predictions from next-to-leading order QCD calculations. Results for heavier quarkonia will also be shown.
