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…

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…
