    abstract = "Results are presented on hyperon and antihyperon production in Pb-Pb,
pPb and pBe collisions at 158 GeV/c per nucleon. Lambda, Xi and Omega
yields have been measured at central rapidity and medium transverse
momentum as functions of the centrality of the collision. Comparing the
yields in Pb-Pb to those in pBe interactions, strangeness enhancement is
observed. The enhancement increases with the centrality and with the
strangeness content of the hyperons, reaching a factor of about 20 for
the Omega in the central Pb-Pb collisions."
