Abstract
The production ofK 0, 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 ofx F andW 2. Most features of the data can be well described by the Lund model. Within this model, the data on the K0/π± ratios and on the averageK 0 multiplicity in the forward region favor a strangeness suppression factors/u in the fragmentation process near 0.20. Clear evidence for QCD effects is seen in the average squared transverse momentum ofK 0 and Λ particles.
