Multi-strange baryon and antibaryon production is expected to be a useful probe in the search for quark-gluon plasma formation. We present the transverse mass distributions of negative particles, LAMBDAs, LAMBDAs-BAR and XI-s produced in sulphur-tungsten interactions at 200 GeV/c per nucleon and give the corrected ratios LAMBDA-BAR/LAMBDA, XI-/LAMBDA and XI--BAR/LAMBDA-BAR. Our ratio XI--BAR/LAMBDA-BAR appears to be larger than that from pp interactions.

Abstract
Multi-strange baryon and antibaryon production is expected to be a useful probe in the search for quark-gluon plasma formation. We present the transverse mass distributions of negative particles, LAMBDAs, LAMBDAs-BAR and XI-s produced in sulphur-tungsten interactions at 200 GeV/c per nucleon and give the corrected ratios LAMBDA-BAR/LAMBDA, XI-/LAMBDA and XI--BAR/LAMBDA-BAR. Our ratio XI--BAR/LAMBDA-BAR appears to be larger than that from pp interactions.File in questo prodotto:
