PWG-DQ (Dileptons and Quarkonia)
Inclusive \jpsi production cross section compared with calculations for the prompt \jpsi production cross section using ICEM~, NLO NRQCD~, LO NRQCD+CGC~ and for the non-prompt \jpsi from beauty-hadron feed-down using FONLL~ (left panel). Inclusive \jpsi production cross section compared with the corresponding calculations obtained as the sum of the prompt \jpsi component shown in the left panel and the non-prompt contribution from FONLL (right panel). The bottom panel shows the ratios between the model calculations and a fit to the data points. The bands illustrate the theoretical uncertainties centered around the ratio between the model calculation and the power-law fit to the data (see text for details).
