First measurements of J/Psi decays into $Σ^{+} Σ ˉ^{-}$ and $Ξ^{0} Ξ ˉ^{0}$

BES Collaboration

Based on 58 million J/Psi events collected with the BESII detector at the BEPC, the baryon pair processes J/Psi to $Σ^{+} Σ ˉ^{-}$ and J/Psi to $Ξ^{0} Ξ ˉ^{0}$ are observed for the fir…

Direct Measurements of Absolute Branching Fractions for D0 and D+ Inclusive Semimuonic Decays

BES Collaboration, M. Ablikim

By analyzing about 33 $p b^{- 1}$ data sample collected at and around 3.773 GeV with the BES-II detector at the BEPC collider, we directly measure the branching fractions for the…

Study of Jψdecaying into ωp \bar p

BES Collaboration

The decay $J / ψ \to ω p p ˉ$ is studied using a $5.8 \times 1 0^{7}$ $J / ψ$ event sample accumulated with the BES II detector at the Beijing electron-positron collider. The decay branc…

Search for the C-parity violating process J/psi->gamma gamma via psi(2S)->pi+pi- J/psi

M. Ablikim, J. Z. Bai

Using 14.0\times 10^6 ψ(2S) events collected with the BES-II detector, the C-parity violating process J/psi->gamma gamma via psi(2S)->pi+pi- J/psi is studied. We determine a new up…

Measurements of $J / ψ$ and $ψ (2 S)$ decays into $Λ Λ ˉ π^{0}$ and $Λ Λ ˉ η$

BES Collaboration, M. Ablikim

Using 58 million $J / ψ$ and 14 million $ψ (2 S)$ events collected by the BESII detector at the BEPC, branching fractions or upper limits for the decays $J / ψ$ and $ψ (2 S) \to Λ Λ ˉ π^{0}$ …

Measurements of the continuum $R_{uds}$ and $R$ values in $e^{+} e^{-}$ annihilation in the energy region between 3.650 and 3.872 GeV

M. Ablikim et al

We report measurents of the continuum $R_{uds}$ near the center-of-mass energy of 3.70 GeV, the $R_{uds (c) + ψ (3770)} (s)$ and the $R_{had} (s)$ values in $e^{+} e^{-}$ annihi…
