Study of J\psi decaying into \omega p \bar p

The decay $J\mathrm{/}\psi \to \omega p\bar{p}$ is studied using a $5.8\times {10}^7$ $J\mathrm{/}\psi$ event sample accumulated with the BES II detector at the Beijing electron-positron collider. The decay branching fraction is measured to be $B(J\mathrm{/}\psi \to \omega p\bar{p})=(9.8\pm 0.3\pm 1.4)\times {10}^{-4}$. No significant enhancement near the $p\bar{p}$ mass threshold is observed, and an upper limit of $B(J\mathrm{/}\psi \to \omega X(1860))B(X(1860)\to p\bar{p})$$ $$< 1.5 \times 10^{-5}$ is determined at the 95% confidence level, where X(1860) designates the near-threshold enhancement seen in the $p\bar{p}$ mass spectrum in $J\mathrm{/}\psi \to \gamma p\bar{p}$ decays.
