Measurements of J/ψdecays into ωK \bar{K} πand ϕK \bar{K} π

BES Collaboration

The decays of $J / ψ \to ω K K ˉ π$ and $J / ψ \to ϕ K K ˉ π$ are studied using $5.8 \times 1 0^{7}$ $J / ψ$ events collected with the Beijing Spectrometer (BESII) at the Beijing Electron…

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…

Production of $σ$ in $ψ (2 S) \to π^{+} π^{-} J / ψ$

BES Collaboration, M. Ablikim

Using 14M $ψ (2 S)$ events accumulated by BESII at the BEPC, a Covariant Helicity Amplitude Analysis is performed for $ψ (2 S) \to π^{+} π^{-} J / ψ, J / ψ \to μ^{+} μ^{-}$ . The $π^{+} π^{-}$ mass spectrum,…

Improved measurement of $ψ (2 S)$ decays into $τ^{+} τ^{-}$

BES Collaboration, M. AblikimJ

Using 14M $ψ (2 S)$ events collected at BESII, the branching fraction of $ψ (2 S) \to τ^{+} τ^{-}$ is measured to be $B r_{τ τ} = (3.10 \pm 0.21 \pm 0.38) \times 1 0^{- 3}$ , where the first error…

Pseudoscalar production at omega omega threshold in J/psi -> gamma omega omega

Bes Collaboration

The decay channel J/ψ->gamma omega omega, omega -> pi+ pi- pi0 is analyzed using a sample of 5.8x10^7 J/psi events collected with the BESII detector. The omega omega invariant mass…
