Using a sample of $(225.2±2.8)×10^6$ $J/\psi$ events collected with the BESIII detector, we present results of a study of $J/\psi→\gamma\mathit{\Lambda\overline{\Lambda}}$ and report the first observation of the isospin ...
• (American Physical Society, 2012)
Using a sample of $106×10^6$ $\psi(3686)$ events collected with the BESIII detector at the BEPCII storage ring, we have made the first measurement of the $M1$ transition between the radially excited charmonium $S-wave$ ...

The decays $J/{\psi}{\rightarrow}p\bar{p}$ and $J/{\psi}{\rightarrow}n\bar{n}$ have been investigated with a sample of $225.2×10^6$ $J/{\psi}$ events collected with the BESIII detector at the BEPCII $e^+e^-$ collider. The ...

Based on a data sample of $106×10^6$ $\psi '$ events collected with the BESIII detector, the decays $\psi '\rightarrow\gamma\chi_{c0,2}, \chi_{c0,2}\rightarrow\gamma\gamma$ are studied to determine the two-photon widths ...
