Double-strangeness production in {bar p}Xe annihilation at low energy in the DIANA chamber
- Institute of Theoretical and Experimental Physics, Moscow (Russian Federation); and others
From the analysis of about 10{sup 5} annihilations of antiprotons at rest and in flight (0.4 - 0.9 GeV/c) on Xe nuclei, new results are presented for the final state K{sup 0}{sub s}SX (S = K{sup 0}{sub s}, K{sup {minus}}, {Lambda}, {Sigma}{sup 0}, {Sigma}{sup +-}). From these results and from earlier results for the final state K{sup +}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 reported earlier in the final states K{sup +}K{sup +}X and K{sup +}K{sup 0}{sub s}{Lambda}X and based on an analysis of 5.4 x 10{sup 5} annihilations, three new events were found in a further analysis of 10{sup 5} annihilations. The new events, together with the revised yields and momentum and mass distributions, are presented. The results confirm earlier results on the effective mass of {Lambda}{Lambda} and a determination of the preferable cascade process.
