Decays of theψ(3097)to baryon-antibaryon final states

A high-statistics study of $\psi$ decays into baryon final states has been done with the Mark II detector at SPEAR. A detailed test of baryon-antibaryon decay modes is presented. Substantial resonance formation is observed in multibody decays of the $\psi$ involving baryons. Branching ratios for a large number of decay modes are given, including the radiative decay $\psi \to p\overline{p}\gamma$. The flavor-SU(3)-forbidden decays $\psi \to {\Sigma }^{\pm }\mathrm{}\left(1385\right)\mathrm{}{\overline{\Sigma }}^{\mp }$+charge conjugate are observed with substantial branching ratios.
