摘要

Recent experimental results from Beijing Spectroscopy (BES) are reviewed,in-cluding the hadron spectroscopy from J/ψdecays,and a number of new states are found or confirmed,including σ,κ;X(1835),ωψ threshold enhancement in J/ψ→γωψ,a broad resbnance in J/ψ→K+K-π0,decay studies of ψ(2S) and χCJ,as well as the results of ψ(3770) non-DD decays.The current status of BEPCⅡ/BESⅢ,the major upgrade of BEPC/BESⅡ,is also reported.
