Recent Results of $\psi (2S)$ Decays from BES

Abstract

Results of many $\psi (2S)$ hadronic decays and the results of $\psi (2S)$ radiative/hadronic transitions from BES collaboration in the past year are presented. Measurement of $\BR(\jpsi\ra K^0_S K^0_L)$ and the preliminary result of searching for the decay $ψ(3770)\raρπ$ are also reported.
