摘要
We reported the observation of Y (2175) in phi f(0)(980) mass spectrum in J/psi -> eta phi f(0)(980) with f(0)(980) -> pi(+)pi(-), the partial wave analysis results of J/psi -> gamma phi phi, the measurement of J/psi -> omega K ($K) over bar pi, phi K (K) over bar pi, and the observation of K- (Lambda) over bar threshold enhancement in J/psi -> pK(-)(Lambda) over bar, based on 5.8 x 10(7) J/psi events collected at BESII. The measurement of psi(2S) radiative decays with 1.4 x 10(7)psi(2S) events as well as the measurement of D decay branching fractions with 33 pb(-1) data collected at and around 3.773 GeV are also presented.
