Based on 5.8×107J/ψ events detected in BESII, the branching fractions of J/ψ→ϕη and ϕη′ are measured for different η η′ decay modes. The results significantly higher than previous measurements. An upper limit B(J/ψ→ϕπ0) is also obtained.3 MoreReceived 15 October 2004DOI:https://doi.org/10.1103/PhysRevD.71.032003©2005 American Physical Society
Using data samples collected at $\sqrt{s}=3.686\text{ }\text{ }\mathrm{GeV}$ and 3.650 GeV by the BESII detector BEPC, branching fraction of $\ensuremath{\psi}(2S)\ensuremath{\rightarrow}3({\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}})$ is measured to be $[5.45\ifmmode\pm\else\textpm\fi{}0.42(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}0.87(\mathrm{syst})]\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$, relative...
