Inclusive production of neutral strange particles in antideuteron-nuclei interactions at 12.2 GeV/c

The data on inclusive production of Λ and K0s in antideuteron-deuteron, antideuteron-carbon and antideuteron-lead interactions at 12.2 GeV/c are reported. The results are given on relative yields, rapidity distribution, average multiplicities of associated charged particles, and kinematical characteristics of neutral strange particles. The possible difference of production mechanisms for K0s- and Λ-particles, as well as the enhancement of Λ-hyperons yield in events with the developed cascade, are also discusses. The data were obtained while irradiating the 2 m bubble chamber LUDMILA with a separated antideuteron beam at the Serpukhov accelerator. 25 refs., 10 figs., 6 tabs
