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 qq and Gamma(4S) decay. For qq events the Theta(1540)(+) [Xi(5)(1860)(--)] limit is about 8 [4] times lower than the rates measured for ordinary baryons of similar mass.
我们在PEP-II正负电子存储环上使用BABAR探测器记录的123飞靶^{-1}数据中，寻找先前其他实验报道过的奇异五夸克态——Θ(1540)^{+}、Ξ_{5}(1860)^{--}和Ξ_{5}(1860)^{0}。我们没有发现这些态的证据，并对每次正负电子湮灭产生qq和Γ(4S)衰变时产生的Θ(1540)^{+}和Ξ_{5}(1860)^{--}五夸克数量设定了95%置信水平的上限。对于qq事件，Θ(1540)^{+}[Ξ_{5}(1860)^{--}]的上限比质量相近的普通重子的测量产率低约8[4]倍。
