Systematics of Exotic Cascade Decays

Theoretical considerations prompted by discovery of the exotic Theta(uudds*) baryon led us to propose a dynamical picture emphasizing the role of diquark correlations, which are also useful in elucidating other aspects of low-energy QCD. A notable prediction of this picture is the existence of new exotic and non-exotic S=-2 ``cascade'' baryons with specific, characteristic properties. We argue here that recent observations by the NA49 collaboration are broadly consistent with our predictions, and propose further tests.
