Abstract

K-S(0), Lambda, Xi, Omega and negative particle yields and transverse massspectra have been measured at central rapidity in Pb-Pb and p-Pb collisions at 158 A GeV/c. Yields are studied as a function of the number of nucleons participating in the collision N-part, which is estimated with the Glauber model. From p-Fb to Pb-Pb collisions the particle yields per participant increase substantially, The enhancement is more pronounced for multistrangeparticles, and exceeds an order of magnitude for the Omega. For a number of participants, N-part, greater than 100, however, all yields per participant appear to be constant. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
