Search for K_S K_S in J/psi and psi(2S) decays
J. Z. Bai, BES Collaboration
The CP violating processes J/psi-->K_S K_S and psi(2S)-->K_S K_S are searched for using samples of 58 million J/psi and 14 million psi(2S) events collected with the Beijing Spectro…
Measurements of decays into Vector- Tensor final states
J. Z. Bai et al
Decays of the into vector plus tensor meson final states have been studied with 14 million events collected with the BESII detector. Branching fractions of $ψ(2S) \…
First Evidence of Lambda Lambda-bar in χ_cJ Decays
BES Collaboration, J. Z. Bai
The first observation of χ_cJ (J=0,1,2) decays to Lambda Lambda-bar is reported using ψ(2S) data collected with the BESII detector at the BEPC. The branching ratios are determined…
Search for Lepton Flavor Violation Process J/
J. Z. Bai
Using a sample of 5.8X10E7 J/ events, the Beijing Spectrometer experiment has searched for the decay J/. Four candidates, consistent with the estimated background, are…
Measurements of the Mass and Full-Width of the Meson
J. Z. Bai
In a sample of 58 million events collected with the BES II detector, the process J/ is observed in five different decay channels: , ,…
