| 英文摘要 | The decay J/psi ->omega p (p) over bar is studied using a 5.8x10(7) J/psi event sample accumulated with the BES II detector at the Beijing Electron-Positron Collider. The decay branching fraction is measured to be B(J/psi ->omega p (p) over bar)=(9.8 +/- 0.3 +/- 1.4)x10(-4). No significant enhancement near the p (p) over bar mass threshold is observed, and an upper limit of B(J/psi ->omega pX(1860))B(X1860)-> p (p) over bar)< 1.5x10(-5) is determined at the 95% confidence level, where X(1860) designates the near-threshold enhancement seen in the p (p) over bar mass spectrum in J/psi ->gamma p (p) over bar decays. |
