| 英文摘要 | Results are presented on psi(2S) and J/psi hadronic decays to K(S)(0)pK(-) (n) over bar and K-S(0)(p) over barK(+)n final states from data samples of 14 million psi(2S) and 58 million J/psi events accumulated at the BES II detector. No Theta(1540) signal, the pentaquark candidate, is observed, and upper limits are set for B(psi(2S)-->Theta(Theta) over bar -->K(S)(0)pK(-)(n) over bar +K-S(0)(p) over barK(+)n)<0.84x10(-5) and B(J/psi-->Theta(Theta) over bar -->K(S)(0)pK(-)(n) over bar +K-S(0)(p) over barK(+)n)<1.1x10(-5) at the 90% confidence level. For single Theta(1540) production, the upper limits determined by our analysis are also on the order of 10(-5) in both psi(2S) and J/psi decays. |
