First observation of psi(2S)-->K_S K_L

J. Z. Bai

The decay psi(2S)-->K_S K_L is observed for the first time using psi(2S) data collected with the Beijing Spectrometer (BESII) at the Beijing Electron Positron Collider (BEPC); the…

Measurement of Branching Ratios for $η_{c}$ Hadronic Decays

J. Z. Bai

In a sample of 58 million $J / ψ$ events collected with the BES II detector, the process J/ $ψ \to γ η_{c}$ is observed in five decay channels: $η_{c} \to K^{+} K^{-} π^{+} π^{-}$ , $π^{+} π^{-} π^{+} π^{-}$ , $K^\…

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/ $ψ \to e μ$

J. Z. Bai

Using a sample of 5.8X10E7 J/ $ψ$ events, the Beijing Spectrometer experiment has searched for the decay J/ $ψ \to e μ$ . Four candidates, consistent with the estimated background, are…
