Title: Dibaryons with Strangeness: Their Weak Nonleptonic Decay Using SU(3) Symmetry and How to Find Them in Relativistic Heavy-Ion Collisions

Abstract

Weak SU(3) symmetry is successfully applied to the weak hadronic decay amplitudes of octet hyperons. Weak nonmesonic and mesonic decays of various dibaryons with strangeness, their dominant decay modes, and lifetimes are calculated. Production estimates for the Brookhaven Relativistic Heavy Ion Collider are presented employing wave-function coalescence. Signals for detecting strange dibaryon states in heavy-ion collisions and revealing information about the unknown hyperon-hyperon interactions are outlined. (c) 2000 The American Physical Society.
