Measurements of $J\psi$ decays into $\omega {\pi }^0$, $\omega \eta$, and $\omega {\eta }^{\prime }$

Abstract

Based on $5.8\times 10^{7}J\psi$ events collected with BESII at the Beijing Electron-Positron Collider (BEPC), the decay branching fractions of $J\psi \to \omega {\pi }^0$, $\omega \eta$, and $\omega {\eta }^{\prime }$ are measured using different $\eta$ and ${\eta }^{\prime }$ decay modes. The results are higher than previous measurements. The $\omega {\pi }^0$ electromagnetic form factor is also obtained.
