Abstract
We have measured rapidity densities of and over a broad rapidity range () for central collisions at . These data have significant implications for the chemistry and dynamics of the dense system that is initially created in the collisions. The full phase-space yields are (), (), (), and (). The systematics of the strange to nonstrange meson ratios are found to track the variation of the baryochemical potential with rapidity and energy. Landau-Carruthers hydrodynamics is found to describe the bulk transport of the pions in the longitudinal direction.
