Baryon Spectroscopy at Beijing Electron Positron Collider

Abstract

BES Collaboration has collected 58 million $J/\psi$ events at the Beijing Electron-Positron Collider (BEPC). $J/\psi$ decays provide an excellent place for studying excited nucleons and hyperons -- $N^{\ast }$, ${\Lambda }^{\ast }$, ${\Sigma }^{\ast }$ and ${\Xi }^{\ast }$ resonances. Physics motivation, data status, partial wave analyses and future prospects are presented for the baryon resonance program at BES.
