| Abstract: | Cross sections, mass spectra, angular distributions and several other features of Ξ? and Ω? production from photons and neutrons in K?d interactions at 4.93 GeV/c are presented. A five standard deviation peak is observed in ΞKπ mass spectra near 2.6 GeV/c2. A sharp rise in the Ξ? three- and four-body cross sections from K?n interactions suggests direct-channel Σ1 (3.0–3.5) formation. |
