Summary
The authors present a preliminary inclusive search for strange pentaquark production in e⁺e⁻ interactions at a center-of-mass energy of 10.58 GeV using 123 fb⁻¹ of data collected with the BABAR detector. They look for the states that have been reported previously: the Θ⁺(1540), interpreted as a udud{bar s} state; and the Ξ⁻⁻(1860) and Ξ°(1860), candidate dsds{bar u} and uss(u{bar u} + d{bar d}) states, respectively. In addition they search for other members of the antidecuplet and corresponding octet to which these states are thought to belong. They find no evidence for the production of such states and set preliminary limits on their production cross sections as functions of c.m. momentum. The corresponding limits on the Θ⁺(1540) and Ξ⁻⁻(1860) rates per e⁺e⁻ --> q{bar q} event are well below the rates measured for ordinary baryons of similar mass.
