N* and Meson Resonances in J/psi decays

Abstract

Over sixty million J/psi events have been collected by the BES Collaboration at the Beijing Electron-Positron Collider (BEPC). J/psi decays provide an excellent place for studying excited nucleons and hyperons -- N*, ${\Lambda }^{\ast }$, ${\Sigma }^{\ast }$ and ${\Xi }^{\ast }$ resonances, as well as meson resonances, including possible glueballs and hybrids. Physics objectives, recent results and future prospects of light hadron spectroscopy at BEPC are presented.
