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…
