摘要：
The role of higher Fock-state contributions to exclusive charmonium decays will be discussed. It will be argued that the J/psi (psi ') decays into baryon-antibaryon pairs are dominated by the valence Fock-state contributions. P-wave charmonium decays, on the other hand, receive strong contributions from the c (c) over bar g Fock states since the valence Fock-state contributions are suppressed in these reactions. Numerical results for the decay widths of J/psi(psi ') --> B (B) over bar and chi(cJ) (-->) P (P) over bar will be also presented and com pared to data.
