Abstract:Recent experimental results from Beijing Spectroscopy (BES) are reviewed, including the hadron spectroscopy from J/ψ decays, and a number of new states are found or confirmed, including σ, κ, X(1835), ωφ threshold enhancement in J/ψγωφ, a broad resonance in J/ψK + K π 0, decay studies of ψ(2S) and χ CJ , as well as the results of ψ(3770) non-D $$
