Abstract
- The production of ?, <img src="/fulltext-image.asp?format=htmlnonpaginated&src=RH851690K3711546_html\10052_2005_Article_BF01554465_TeX2GIFIE1.gif" border="0" alt=" $$\bar \Lambda$$ " /> andK<subscript>s</subscript><superscript>0</superscript> has been studied in 200 GeV/nucleonp+S and S+S collisions in the streamer chamber of the NA35 experiment at the CERN SPS. Significant enhancement of the multiplicities of all observed strange particles relative to negative hadrons was observed in central S+S collisions, as compared top+p andp+S collisions. The latter collisions show no overall (relative) strangeness enhancement overp+p, but the rapidity distributions and hadron multiplicities indicate some secondary cascading production of ? particles in thep+S andp+Au collisions. The ? polarization in central S+S collisions was found to be compatible with zero up top<subscript>T</subscript>=2 GeV/c.
