Abstract

The production properties of Ks0, {Mathematical expression} and K+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. The x-, pT-, and transverse mass dependence of inclusive and semi-inclusive distributions is discussed as well as properties of "prompt"Ks0's. The ratio of "prompt"K890+ (K8900) to "prompt"K0 cross sections is measured to be 1.03±0.12 (0.98±0.17). From a comparison of {Mathematical expression} production in K±p interactions at 32 GeV/c, we estimate a strange sea-quark suppression of 0.26 ±0.02. The double differential cross sections of Ks0's is studied as a function of Feynman-x and pT2, and a Triple-Regge fit performed. The data are compared in detail to versions of the Lund-model for low-pT hadronic collisions.
