Abstract: (arXiv)
Results are presented on and hadronic decays to and final states from data samples of 14 million and 58 million events accumulated at the BES II detector. No signal, the pentaquark candidate, is observed, and upper limits for and at the 90% confidence level are set. For single production, the upper limits determined by our analysis are also on the order of in both and decays.- 14.20.Jn
