Abstract

The production of K0, Λ and {Mathematical expression} particles is studied in the E665 muon-nucleon experiment at Fermilab. The average multiplicities and squared transverse momenta are measured as a function of xF and W2. Most features of the data can be well described by the Lund model. Within this model, the data on the K0± ratios and on the average K0 multiplicity in the forward region favor a strangeness suppression factor s/u in the fragmentation process near 0.20. Clear evidence for QCD effects is seen in the average squared transverse momentum of K0 and Λ particles.
