Measurement of the branching fractions for $J / ψ \to γ π^{0}$ , $γ η$ and $γ η^{'}$

M. Ablikim, J. Z. Bai, BES Collaboration

The decay modes $\jpsi\arγπ^0, γη$ and $γ\etap$ are analyzed using a data sample of 58 million $\jpsi$ decays collected with the BESII detector at BEPC. The branching fractions are…

Obervation of χ_{cJ}--> omega omega decays

BES Collaboration, M. Ablikim

Decays of $χ_{c0,2}\ar\ww$ are observed for the first time using a sample of $14.0 \times 1 0^{6}$ $ψ (2 S)$ events collected with the BESII detector. The branching ratios are determined…
