The CERN experiment WA97, which studies strange particle production at central rapidity in Pb-Pb, p-Pb, p-Be collisions at 158 A GeV/c, has already reported a pronounced enhancement of hyperon production. This is considered a sensitive signature for a phase transition to a new state of matter - the Quark Gluon Plasma (QGP). A comprehensive study, including the most recent results, of yields and transverse mass spectra of K-S(0), Lambda, Xi (-), Omega (-) (and antiparticles) and negative particles as a function of the number of nucleons partecipating in the collisions is presented.
