The E885 collaboration utilized the 1.8 GeV/c K- beam line at the AGS to ac cumulate greater than 10 times the world's existing data sample of (K-,K+) events on carbon. The data were used to search for signatures of the produc tion of Xi hypernuclei, double-Lambda hypernuclei, and H Dibaryons. Evidenc e for the creation of Be-12(Xi) is seen. Reasonable agreement between the d ata and theory is achieved by assuming a Xi-nucleus Wood-Saxon potential we ll depth, V-0 Xi, of about 14 MeV. Upper limits for the production of doubl e-Lambda hypernuclei are presented. Upper limits for H-Dibaryon production are presented which are a factor of 50 below calculated rates.
