Abstract

We report partial wave analysis results for J/ψγK+KJ/\psi \to \gamma K^+ K^- based on 7.8×1067.8 \times 10^6 BESI J/ψJ/\psi events, and find 0++0^{++} to be dominant in the fJ(1710)f_J(1710) mass region. Some very preliminary results are presented from the 2.2×1072.2 \times 10^7 J/ψJ/\psi events newly collected at the upgraded BES(BESII). Using the world largest ψ(2S)\psi(2S) data sample, BES measures branching ratios of ψ(2S)\psi(2S) radiative and hadronic decays. The preliminary R values measured by BESII in the 2-5 GeV energy region are also presented.
