In the 1992–1995 runs CDF has collected large samples of J ψ , ψ (2 S ) and ϒ identified through their muonic decay. In the charmonium system all production sources have been separately measured and compared with the theoretical predictions. A large excess of direct production has been observed for both ψ (2 S ) and J ψ . The relative production rate for the χ c 1 and χ c 2 has also been measured. The unexpected results have lead to a profound revisitation of the theory of the production of Q Q bound states in high energy hadronic collisions.
