摘要：

We present in this work a study of large-pr charmonium production in hadronic collisions. We work in the framework of the factorization model of Bodwin, Braaten and Lepage, thereby including the colour octet production mechanism, and extract the values of the necessary non-perturbative parameters from a comparison with the most recent data from the Fermilab 1.8 TeV p (p) over bar hadron collider. We extend the calculation to 630 GeV, and compare the results with data published by the UA1 Collaboration. The global agreement is satisfactory, indicating that the largest components of the mechanisms for charmonium production at high pr have been isolated.
