| Abstract: | The production properties ofK s 0 , \(\bar \Lambda\) andK + p interactions at 32 GeV/c are investigated using the final statistics of the experiment. We present total and semi-inclusive cross sections and aver-age multiplicities. Estimates are given of the diffractive dissociation contributions to total and differential cross sections. Thex-,p T ?, and transverse mass dependence of inclusive and semi-inclusive distributions is discussed as well as properties of “prompt”K s 0 's. The ratio of “prompt”K 890 + (K 890 0 ) to “prompt”K 0 cross sections is measured to be 1.03±0.12 (0.98±0.17). From a comparison of \(\bar \Lambda\) production inK ± p interactions at 32 GeV/c, we estimate a strange sea-quark suppression of 0.26 ±0.02. The double differential cross sections ofK s 0 's is studied as a function of Feynman-x andp T 2 , and a Triple-Regge fit performed. The data are compared in detail to versions of the Lund-model for low-p T hadronic collisions. |
