Abstract: The production of K, Λ and $$\bar \Lambda $$ particles is studied in the E665 muon-nucleon experiment at Fermilab. The average multiplicities and squared transverse momenta are measured as a function of x and W. Most features of the data can be well described by the Lund model. Within this model, the data on the K/π ratios and on the average K 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 K and Λ particles. [ABSTRACT FROM AUTHOR]
