摘要We search for strange-pentaquark states that have been previously reported by other experiments-the Theta(1540)(+), Xi(5)(1860)(--), and Xi(5)(1860)(0)-in 123 fb(-1) of data recorded with the BABAR detector at the PEP-II e(+)e(-) storage ring. We find no evidence for these states and set 95% confidence level upper limits on the number of Theta(1540)(+) and Xi(5)(1860)(--) pentaquarks produced per e(+)e(-) annihilation into q (q) over bar and per Upsilon(4S) decay. For q (q) over bar events the Theta(1540)(+) [Xi(5)(1860)(--)] limit is about 8 [4] times lower than the rates measured for ordinary baryons of similar mass.
