Abstract: (APS)
Evidence is presented for four Ξ resonances in the reaction K−p→Ξ−π+K0. In addition to the well known Ξ(1530), significant structures are observed in the Ξπ system at masses of 1630, 1800, and 1960 MeV, although the latter two are not statistically distinguishable from a single broad structure at 1950 MeV. No significant enhancements at these masses are observed in the Ξ−π0K+ final state.
