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/c^2. Finding no evidence for such a state in the mass range of 1480 MeV/c^2 to 2400 MeV/c^2, we set limits on the yield and on the cross section times branching ratio relative to $Ξ^*(1530)^0$.
