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,…

Measurements of psi(2S) decays to octet baryon-antibaryon pairs

The BES Collaboration, M. Ablikim

With a sample of 14 million psi(2S) events collected by the BESII detector at the Beijing Electron Positron Collider (BEPC), the decay channels psi(2S)->p p-bar, Lambda Lambda-bar,…
