摘要：
The role of power corrections and 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 barg$ Fock states since the valence Fock-state contributions are suppressed in these reactions. Numerical results for J/psi (psi') --> <B(B)over bar> decay widths will be also presented and compared to data.
