| Abstract: | Within the NRQCD factorization approach the production of heavy quarkonia can be calculated in perturbative QCD in terms
of a few production-process-independent NRQCD matrix elements. We test the universality of these long-distance matrix elements
by comparing their values as determined from charmonium production at , ep, and colliders, and in , , and B decays.
