摘要

The production properties of lambdas (LAMBDA0, LAMBDA0BAR) and cascades (XI-,XI-BAR) in the central region in ppBAR collisions at square-root s = 1.8 TeV at the Fermilab collider are reported. The transverse-momentum spectra of lambdas are measured as a function of multiplicity and the ratios of lambdas to protons (p,pBAR) and to all charged particles are studied as a function of transverse momentum and multiplicity. Moreover the average transverse momentum of cascades and the ratio of cascades to lambdas are presented.
