 Rapidity distributions around mid-rapidity of strange particles in Pb-Pb collisions at 158 $A$ GeV/c
 NA57 Collaboration(s)
 (2005)
 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. The distributions are analyzed based on hydrodynamical models of the collisions.
