Strangeness production in sulphur-tungsten interactions at 200 GeV/c per nucleon

Abstract Preliminary results from the WA85 Experiment at the CERN Omega Spectrometer are presented. A 200 A GeV/c beam of 22 S ions was used with a tungsten target. The apparatus is used to detect V°s and charged tracks in the range P T > 0.9 GeV/c and 2.3 lab Λ, Λ and cascade particles is discussed. A study of the multiplicity dependence of Λ, Λ and hadron production is presented.
