Abstract
Charged and neutral strange particle production was studied by the NA49 exp eriment at CERN. Preliminary inclusive spectra are presented for K+/-, K-S( 0), Phi, Lambda, <(Lambda)over bar> and Xi(+/-) particles, measured in a re gion close to mid-rapidity, for central Pb+Pb collisions at 158 GeV per nuc leon. An enhanced strange particle production relative to properly scaled e lementary nucleon-nucleon collisions is observed, but its strength is simil ar to lighter S + nucleus systems. The enhancement is stronger for multistr ange particles.
