Baryonic Decays of Charmonium - a Window on Internal Baryon Structure

Abstract

The baryonic decays of $J/\psi$ provide a new way to study the internal structure of baryons. A simple diquark model applied to the calculation of the $\bar{B}B$ decay cross-sections is compared with the ordinary constituent quark model. Various models also give different predictions for the rates involving the $N^{\ast }(1440)$ resonance in the final state.
