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…

Measurements of branching fractions for inclusive K0~/K0 and K*(892)+- decays of neutral and charged D mesons

M. Ablikim

Using the data sample of about 33 pb-1 collected at and around 3.773 GeV with the BES-II detector at the BEPC collider, we have studied inclusive K0~/K0 and K*(892)+- decays of D0…

Direct measurement of the absolute branching fraction for $D^{+} \to K ˉ^{0} μ^{+} ν_{μ}$ and determination of $Γ (D^{0} \to K^{-} μ^{+} ν_{μ}) /Γ (D^{+} \to K ˉ^{0} μ^{+} ν_{μ})$

M. Ablikim

The absolute branching fraction for the decay $D^{+} \to K ˉ^{0} μ^{+} ν_{μ}$ is determined using $5321 \pm 149 \pm 160$ singly tagged $D^{-}$ sample from the data collected around 3.773 G…
