Enhancement of hyperon production at central rapidity in 158 A GeV/c Pb-Pb collisions / NA57 Collaboration
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. [...]

Strangeness enhancements at central rapidity in 40 A GeV/c Pb-Pb collisions / NA57 Collaboration
Results are presented on neutral kaon, hyperon and antihyperon production in Pb-Pb and p-Be interactions at 40 GeV/c per nucleon. The enhancement pattern follows the same hierarchy as seen in the higher energy data - the enhancement increases with the strangeness content of the hyperons and with the centrality of collision.

Rapidity distributions around mid-rapidity of strange particles in Pb-Pb collisions at 158 $A$ GeV/c / NA57 Collaboration
The production at central rapidity of K0s, Lambda, Xi and Omega particles in Pb-Pb collisions at 158 A GeV/c has been measured by the NA57 experiment over a centrality range corresponding to the most central 53% of the inelastic Pb-Pb cross section. In this paper we present the rapidity distribution of each particle in the central rapidity unit as a function of the event centrality. [...]

Study of the transverse mass spectra of strange particles in Pb-Pb collisions at 158 A GeV/c / NA57 Collaboration
The NA57 experiment has collected high statistics, high purity samples of \PKzS and \PgL, $\Xi$ and $\Omega$ hyperons produced in Pb-Pb collisions at 158 $A$ GeV/$c$. In this paper we present a study of the transverse mass spectra of these particles for a sample of events corresponding to the most central 53% of the inelastic Pb-Pb cross-section. [...]

New results from NA57 / Bruno, G.E. (Bari Polytechnic ; INFN, Bari) /NA57 Collaboration
The production of hyperons in Pb-Pb and p-Be interaction at 40 A GeV/c beam momentum has been measured by the NA57 experiment. Strange particle enhancements at 40 A GeV/c are presented for the first time and compared to those measured at 158 A GeV/c. [...]

Transverse dynamics of Pb-Pb collisions at 40 A GeV/c viewed by strange hadrons / NA57 Collaboration
The transverse mass spectra of K0s, Lambda, Xi and Omega particles produced in Pb-Pb collisions at 40 A GeV/c have been studied for a sample of events corresponding to the most central 53% of the inelastic Pb-Pb cross-section. We analyze the distributions in the framework of a parameterized model inspired by hydrodynamics. [...]

The NA57 experiment has measured strange baryon and antibaryon production in Pb-Pb collisions at 40 A GeV/c and 160 A GeV/c beam momenta. This presentation covers strangeness enhancement and transverse spectra from the 160 A GeV/c data, and energy dependence of the particle yields. [...]

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). [...]
