Recent $J/\psi$ Results from BESII

Abstract

The studies on the multi-quark candidates, light scalar mesons and excited baryon states at BES are presented, based on $5.8 \times 10^7$ $J/\psi$ data collected with BESII detector. The measurements of some $J/\psi$ and $\eta_c$ decays are presented too. We also report the searches for the lepton flavor violation and pentaquark states in $J/\psi$ decays.
