Evidence of Xi hypernuclear production in the 12C(K-,K+)12XiBe reaction
Abstract
The E885 collaboration utilized the 1.8 GeV/c K- beam line at the AGS to accumulate 3 x 105 (K-,K+) events. Xi hypernuclear states are expected to be produced through the reaction K- + 12C -> K+ + 12XiBe. The measured missing-mass spectrum indicates the existence of a signal below the threshold for free Xi production. Although the resolution was not sufficient to resolve discrete hypernuclear states, the excess of events in the region of missing mass, kinematically inaccessible in free Xi production, is compared to theoretical prediction for 12XiBe production.
