N and Meson Resonances in J/ψ Decays
Abstract
Over sixty million J/ψ events have been collected by the BES Collaboration at the Beijing Electron-Positron Collider (BEPC). J/ψ decays provide an excellent place for studying excited nucleons and hyperons -- N*, Λ*, Σ* and Ξ* 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.
