Observation of a resonance X(1835) in J/ψ--> γπ^+ π^- η^{\prime}
BES Collaboration, M. Ablikim
The decay channel J/ψ--> γπ^+ π^- η^{\prime} is analyzed using a sample of 5.8\times 10^7 Jψevents collected with the BESII detector. A resonance, the X(1835), is observed in the π…

Observation of a threshold enhancement in the p \bar{Lambda} invariant mass spectrum
BES Collaboration, M. Ablikim
An enhancement near the m_p + M_Λ mass threshold is observed in the combined p \barΛ and \bar{p}Λinvariant mass spectrum from J/ψ--> p K^- \bar{Lambda} + c.c. decays. It can be fit…
