Exclusive charmonium decays
Description
The role of power corrections and higher Fock-state contributions to exclusive charmonium decays are discussed. It is argued that the J/ψ (ψ') 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 ccg Fock states since the valence Fock-state contributions are suppressed in these reactions. Numerical results for J/ψ(ψ') → BB decay widths are also presented and compared to data. (orig.)
