RECENT RESULTS FROM BESII
Abstract
We reported the observation of Y(2175) in ϕf0(980) mass spectrum in J/ψ → ηϕf0(980) with f0(980) → π+π-, the partial wave analysis results of J/ψ → γϕϕ, the measurement of ,
, and the observation of
threshold enhancement in
, based on 5.8 × 107 J/ψ events collected at BESII. The measurement of ψ(2S) radiative decays with 1.4 × 107 ψ(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.
