Anomalous Line-Shape of Cross Sections for $e^+e^- \to {\rm Hadrons}$ in the Center-of-Mass Energy Region between 3.650 and 3.872 GeV / BES Collaboration
We observe an obvious anomalous line-shape of the $e^+e^- \to {\rm hadrons}$ total cross sections in the energy region between 3.700 and 3.872 GeV from the data samples taken with the BES-II detector at the BEPC Collider. [...]

Search for the Rare Decays $J/\psi \to D_{S}^{-} \pi^{+}$, $J/\psi \to D^{-} \pi^{+}$, and $J/\psi \to \bar D^{0} \bar K^{0}$ / BES Collaboration
Rare decay modes $J/\psi \to D_{S}^{-} \pi^{+} + c.c.$, $J/\psi \to D^{-} \pi^{+} + c.c.$, and $J/\psi \to \bar D^{0} \bar K^{0} + c.c.$ are searched for using 5.77$\times 10^{7}$ $J/\psi$ events collected with the BESII detector at the BEPC. [...]

Measurements of the absolute branching fractions for the semileptonic decays D0 -> K-mu+nu_mu and D0 -> pi-mu+nu_mu / BES Collaboration
Based on the data sample of 33 pb$^{-1}$ collected at and around 3.773 GeV with the BESII detector at the BEPC collider, the absolute branching fractions for the semileptonic decays $D^0\to K^-\mu^+\nu_\mu$ and $D^0\to\pi^-\mu^+\nu_\mu$ have been measured. [...]
