The relative production yields and transverse mass spectra for Λ, Λ , Ξ − and Ξ + hyperons in proton-tungsten interactions are presented and compared with the WA85 results from central sulphur-tungsten interactions. A study of the negative particle yield has also been undertaken and the ratio of Λ hyperons to negative particles has been calculated.

Results on K s 0 production at central rapidity in sulphur-tungsten interactions are presented. The selection procedure used to identify K s 0 particles through their decay to two charged pions is described. The m T spectra for K s 0 , Λ and Λ and the relative production rates K s 0 Λ and K s 0 Λ , calculated in the kinematic region p T > 1 GeV/ c and 2.5 ≤ y LAB ≤ 3.0, are discussed.
