Detecting Strangeness -4 Dibaryon States

Abstract

Recent experiments at Jefferson Laboratory and potential new facilities at the Japan Proton Accelerator Research Complex (J-PARC) make it evident that the discovery of a spin-singlet S-wave di-cascade bound state of two cascade (Xi) particles is feasible. We state the simple arguments, based on SU(3) flavor symmetry, for the existence of this bound state, review the previous predictions and comment on the experimental conditions necessary for detection.
