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,…

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…

Observation of a near-threshold enhancement in the ωϕmass spectrum from the doubly OZI suppressed decay J/ψ\to γωϕ

BES Collaboration

An enhancement near threshold is observed in the ωϕinvariant mass spectrum from the doubly OZI suppressed decays of J/ψ\to γωϕ, based on a sample of 5.8 X 10^7 J/ψevents collected…
