Abstract
- The production ofK<superscript>0</superscript>, ? and <img src="/fulltext-image.asp?format=htmlnonpaginated&src=T015R052WP368W60_html\10052_2005_Article_BF01552620_TeX2GIFIE1.gif" border="0" alt=" $$\bar \Lambda $$ " /> particles is studied in the E665 muon-nucleon experiment at Fermilab. The average multiplicities and squared transverse momenta are measured as a function ofx<subscript>F</subscript> andW<superscript>2</superscript>. Most features of the data can be well described by the Lund model. Within this model, the data on the K<superscript>0</superscript>/p<superscript>±</superscript> ratios and on the averageK<superscript>0</superscript> 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<superscript>0</superscript> and ? particles.
