Strange particle production p-Be, p-Pb, Pb-Pb at 158 A GeV/c (WA97 experiment) / WA97 Collaboration
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 as a sensitive signature for a phase transition to a new state of matter-the quark gluon plasma (QGP). [...]

Strange baryon production in Pb-Pb collisions at 158 A GeV/c / Fini, R A ; Antinori, Federico ; Beutsch, W ; Bloodworth, Ian J ; Caliandro, R ; Carrer, N ; Di Bari, D ; Di Liberto, S ; Elia, D ; Evans, D et al.
The experiment WA97 is dedicated to the study of strange baryon production in Pb-Pb interactions at SPS energy. Results on the production of strange and multistrange baryons at midrapidity in Pb- Pb at 158 A GeV c/sup -1/ are reported and compared with those from p-Pb and p-Be reactions at the same energy. [...]

Production of strange and multistrange hadrons in nucleus-nucleus collisions at SPS / WA97 Collaboration
We report the main results from experiment WA97 on the production of strange and multistrange hadrons at midrapidity in Pb+Pb, p+Pb and p+Be collisions at 158~A~GeV/$c$. A comparison with some of the available models is presented..

Hyperon and negative particle production at central rapidity in proton-beryllium interactions at 158 GeV/c / WA97 Collaboration
A study of the strangeness enhancement in lead-lead collisions with respect to proton-induced reactions is being carried out at the CERN SPS by the WA97 experiment: up to now, data from proton-lead collisions have been used as a reference sample. In this paper we report on a study of particle production in proton-beryllium collisions. [...]

Multi-strange Particle Production In P-be, P-pb, And Pb-pb Collisions At 158 $a$ Gev/c / Antinori, Federico ; Bakke, H ; Beusch, Werner ; Bloodworth, Ian J ; Caliandro, R ; Carrer, N ; Di Bari, D ; Di Liberto, S ; Elia, D ; Evans, D et al.
ΞΞ and ΩΩ particle yields and transverse mass spectra have been measured at central rapidity in p-Be, p-Pb, and Pb-Pb collisions at 158 A GeV /c. Yields are studied as a function of the number of nucleons participating in the collision, NpartNpart, which is estimated using the Glauber model. [...]

Results on hyperon production from CERN NA57 experiment / NA57 Collaboration
NA57 has been specifically designed to study, the onset of strange baryon and antibaryon enhancements in Pb-Pb with respect to p-Be collisions, first observed by the WA97 experiment at 160 A GeV/c beam momentum. The aim is to look for the dependence of these enhancements on the interaction volume, as measured by the number of wounded nucleons, and the energy per incoming nucleon. [...]

Statistical hadronization and strangeness enhancement from p-A $\to$ Pb- Pb collisions / Redlich, Krzysztof ; Hamieh, S ; Tounsi, A
The production of strange particles in Pb-Pb and p-A collisions at the SPS energy is discussed in the context of a statistical hadronization model. We show that the observed enhancement of strange baryon and antibaryon yields in Pb-Pb relative to p-Be and p-Pb collisions reported by the WA97 experiment can be quantitatively described in terms of the model if strangeness conservation is formulated in a canonical ensemble.

Study of strangeness enhancement in lead-lead collisions at the CERN SPS / WA97 Collaboration
A review of the latest results from the WA97 experiment on the strange particle production in Pb-Pb and p-Pb collisions is presented. Transverse mass spectra and yields of K/sub S//sup 0/, Lambda , Xi , Omega and h/sup -/ (negatively charged particles) have been measured at central rapidity. [...]

Strange baryon production from the NA57 experiment at the CERN SPS / NA57 Collaboration
The production of strange baryons and antibaryons in Pb+Pb and p+Be collisions has been studied by the NA57 experiment at the CERN SPS, extending down the centrality range covered by the previous WA97 experiment, and collecting data at two different energies. The enhanced production of such particles in central Pb+Pb collisions with respect to p+Be has been experimentally confirmed. [...]
