Search for a pentaquark decaying to Cascade- pi-

Abstract

We present a search for a pentaquark decaying strongly to -π- in γ N 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 *(1530)0.
