RESULTS ON THE PRODUCTION OF BARYONS WITH VERTICAL-BAR-S-VERTICAL-BAR=1, 2, 3 AND STRANGE MESONS IN S-W COLLISIONS AT 200 GEV/C PER NUCLEON

We report results on the production of strange baryons/antibaryons with 1, 2, and 3 units of strangeness (Lambda, Xi and Omega) and mesons (K-s(0), K+ and K-) in WA85 experiment at the CERN SPS. This experiment was designed to study the production of strange particles in central SW collisions at 200 GeV/c per nucleon, in the central rapidity region with medium to high p(t). We have measured the inverse slopes of the m(t) distributions of such particles and the production ratios <(Lambda)over bar>/Lambda, <(Xi)over bar>(+)/Xi(-), Xi(-)/Lambda, <(Xi)over bar>(+)/<(Lambda)over bar>, K-s(0)/Lambda, K-s(0)/<(Lambda)over bar> (Omega(-) + <(Omega)over bar>(+))/(Xi(-) + <(Xi)over bar>(+)) and K+/K-. Preliminary results on the production ratios Xi(-)/Lambda and <(Xi)over bar>(+)/<(Lambda)over bar> in pW collisions at 200 GeV/c are also presented.
