The production at central rapidity of KS0, L,
X and W particles in Pb-Pb collisions
at 158 AGeV has been measured by the NA57 experiment over a centrality range corresponding to the most
central 53% of the inelastic Pb-Pb cross section. We present the rapidity distribution of each
particle in the central rapidity unit. The distributions are analysed based on hydrodynamical models
of the collisions.
