{Lambda} and {Xi}{sup {minus}} production in proton-tungsten interactions at 200 GeV/c per nucleon

The primary aim of the WA85 experiment is the study of strange and multistrange baryon and anti-baryon production. Particles are detected in the kinematic window of central rapidity and {ital pT}{gt}1.0 GeV/c. Results on the production of {Lambda}, {bar {Lambda}},{Xi}{sup {minus}} and {bar {Xi}}{sup {minus}} hyperons in proton-tungsten interactions from the 1990 run are presented and compared with the sulphur-tungsten data. {copyright} 1995 {ital American} {ital Institute} {ital of} {ital Physics}.
