Evidence for Ξ Resonances in the Ξ(1530)π System
Abstract
Evidence is presented for the decay of the Ξ(1820) and Ξ(1930) resonances to Ξ(1530)π, and for an I=12 assignment to these states. By combining data from the Ξπ and Ξ(1530)π decays of these resonances, we have determined their masses (1820 +/- 7, 1963 +/- 8) MeV, widths (64 +/- 23, 89 +/- 33) MeV, and branching ratios [ΞπΞ(1530)π=1.5+0.6- 0.4, 2.8+0.7-0.6].
