Baryon Spectroscopy at Beijing Electron Positron Collider

B. S. Zou, X. B. Ji, H. X. Yang +1

BES Collaboration has collected 58 million $J / ψ$ events at the Beijing Electron-Positron Collider (BEPC). $J / ψ$ decays provide an excellent place for studying excited nucleons and…

New R Values in 2-5 Gev from the Beijing Spectrometer

G. S. Huang, representing the BES Collaboration

The values of $R = σ (e^{+} e^{-} \to ha d r o n s) / σ (e^{+} e^{-} \to μ^{+} μ^{-})$ for 85 center-of-mass energies between 2 and 5 GeV were measured with the upgraded Beijing Spectrometer at the Beijing…

N* Resonances in e+e- Collisions at Bepc

B. S. Zou, H. B. Li, representing BES Collaboration

$J /Ψ$ particles are abundantly produced at the Beijing Electron Positron Collider (BEPC). The $J /Ψ$ decays provide an excellent place for studying $N^{*}$ resonances. For $J/Ψ\to\bar…
