RECENT RESULTS FROM BESII AND THE STATUS OF BEPCII/BESIII

Abstract

We reported the observation of Y(2175) in ɸf0(980) mass spectrum in J/ψ → ηɸf0(980) with f0(980) → π+π-, the partial wave analysis results of J/ψ → γɸɸ, the measurement of [Formula: see text], [Formula: see text], and the observation of [Formula: see text] threshold enhancement in [Formula: see text], based on 5.8 × 107 J/ψ events collected at BESII. We reported the measurement of ψ(2S) radiative decays with 1.4 × 107 ψ(2S) events and the measurement of D decay branching fractions with 33 pb-1 data collected at and around 3.773 GeV as well. The status of BESIII/BEPCII project is also presented.
