K0(s) and Lambda0 Production Studies in P Anti-p Collisions at S**1/2

The authors present a study of the production of K{sub s}° and [Lambda]° in inelastic p{bar p} collisions at √s = 1800 and 630 GeV using data collected by the CDF experiment at the Fermilab Tevatron. Analyses of K{sub s}° and [Lambda]° multiplicity and transverse momentum distributions, as well as of the dependencies of the average number and (p{sub T}) of K{sub s}° and [Lambda]° on charged particle multiplicity are reported. Systematic comparisons are performed for the full sample of inelastic collisions, and for the low and high momentum transfer subsamples, at the two energies. The p{sub T} distributions extend above 8 GeV/c, showing a (p{sub T}) higher than previous measurements. The dependence of the mean K{sub s}°([Lambda]°) p{sub T} on the charged particle multiplicity for the three samples shows a behavior analogous to that of charged primary tracks.
