Description

We present a search for a pentaquark decaying strongly to Ξ-π- in γN collisions at a center-of-mass energy up to 25 GeV/c2. Finding no evidence for such a state in the mass range of 1480 MeV/c2 to 2400 MeV/c2, we set limits on the yield and on the cross section times branching ratio relative to Ξ*(1530)0
