Observation of Two New N* Peaks in J/psi -> $pp i^{-} n ˉ$ and $p ˉ π^{+} n$ Decays

BES Collaboration

The $π N$ system in decays of $J / ψ \to N ˉ N π$ is limited to be isospin 1/2 by isospin conservation. This provides a big advantage in studying $N^{*} \to π N$ compared with $π N$ and $γN…

Evidence of $σ$ particle in $J / ψ \to ω π π$

BES Collaboration

Based on a sample of 7.8 million BESI $J / ψ$ events, the decay of $J / ψ \to ω π^{+} π^{-}$ is studied. A low mass enhancement in the $π^{+} π^{-}$ invariant mass spectrum recoiling against $ω…
