Open AccessObservation of X(2370) and search for X(2120) in \(J/\psi \rightarrow \gamma K{\bar{K}} \eta '\)
Using a sample of \(1.31\times 10^{9} ~J/\psi \)1.31×109J/ψ events collected with the BESIII detector, we perform a study of \(J/\psi \rightarrow \gamma K{\bar{K}}\eta '\)J/ψ→γKK¯η′. X(2370) is observed in the $$...

Open AccessStudy of J/ψ decaying into ωpp̄
The decay J/ψ→ωpp̄ is studied using a 5.8×107 J/ψ event sample accumulated with the BES II detector at the Bei**g Electron–Positron Collider. The decay branching fraction is measured to be B(J/ψ→ωpp̄)=(9.8±0.3±1...
