Abstract
Lambda, Xi and Omega yields and transverse mass spectra have been meas ured in Pb-Pb and p-Pb collisions at 158 A GeV/c. The yields in Pb-Pb interactions are presented as a function of the collision centrality a nd compared with those obtained from p-Pb collisions. Strangeness enha ncement is observed which increases with centrality and with the stran geness content of the hyperon. (C) 1998 Published by Elsevier Science B.V. All rights reserved.
