DOUBLE-STRANGENESS PRODUCTION IN (P)OVER-BAR-XE ANNIHILATION AT LOW-ENERGY IN THE DIANA CHAMBER

From the analysis of about 10(5) annihilations of antiprotons at rest and in flight (0.4 - 0.9 GeV/c) on Xe nuclei, new results are presente d for the final state K(s)0SX (S = K(s)0, K-, LAMBDA, SIGMA, SIGMA+/-) . From these results and form earlier results for the final state K+SX , inclusive and semiinclusive yields are determined, giving virtually all strange channels. The effective strangeness contents were deduced to be 5.5% at rest and 5.3% in flight. In addition to 14 events report ed earlier in the final states K+K+X and K+K(S)0LAMBAX and based on an analysis of 5.4 x 10(5) annihilations, three new events were found in a further analysis of 10(5) annihilations. The new events, together w ith the revised yields and momentum and mass distributions, are presen ted. The results confirm earlier results on the effective mass of LAMB DALAMBDA and a determination of the preferable cascade process.
