Odorico, R

It is shown that existing difficulties in the perturbative QCD approach to the data for hadronic production of charm are eliminated once the flavor excitation contribution is duly taken into account. A stable calculation of this contribution is presented whose main ingredients are: (i) a QCD Monte Carlo calculation of the evolution of the charm sea, with constraints from the existing F/sub 2/ (charm) data; (ii) use of P/sub T/ data for charmed mesons to fix the vector t/sub min/ cutoff which regulates the vector t similarly ordered 0 divergence in the diagrams. Diffractive production of ..lambda../sub c/ is shown to be naturally understood with a simple recombination model. Qualitative predictions for bottom production are also discussed.
