Brodsky, S J

There are many outstanding discrepancies comparing the predictions of perturbative QCD and measurements of the rate of production and decay of heavy quark systems. The problems include the J/{psi} {r_arrow} {rho}{pi} puzzle, leading charmed particle effects, the anomalous behavior of the heavy quark sea components of structure functions, anomalous nuclear target effects, and the large rates observed for single and double quarkonium production at large x{sub F} and large p{sub T}. The author argues that these anomalies may be associated with nonperturbative effects in the higher Fock structure of hadron wavefunctions. 64 refs.
