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…

Observation of a broad 1^-- resonant structure around 1.5 GeV/ $c^{2}$ in the K^+K^- mass spectrum in J/psi --> K^+K^-pi^0

BES Collaboration, M. Ablikim

A broad peak is observed at low K^+K^- invariant mass in J/psi --> K^+K^-pi^0 decays found in a sample of 5.8\times 10^7 J/psi events collected with the BESII detector. A partial w…

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…
