The production at central rapidity of K0S, Λ, Ξ and Ω 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. The distributions are analysed based on hydrodynamical models of the collisions.

Abstract
The production at central rapidity of K0S, Λ, Ξ and Ω 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. The distributions are analysed based on hydrodynamical models of the collisions.File in questo prodotto:
