Dear Djamel, first I think that you last mail represents an excellent compromise between differing interpretations of our great data. The fact that these data provoke heated discussion means that they are very interesting. Since you mention the total yields I think it is naturel to follow up with the k/pi systematics. Then I would put the hydro stuff at the end. Since PRL wants this to sound exciting to people outside the field I think we need one sentance for them and we should use as little jargon as possible in the absdtract. Thus I would suggest: We have measured the yields of charged pions and kaons from central AuAu collisions at sqrt(Snn)=200GeV over a broad rapidity range (-0.1 < y < 3.5). These data have significant implications for the chemistry and dynamics of the hot dense system that is initially created in the collisions. The full phase--space yields are 1742 +-17 +- 140 (pi+), 1761 +- 16 +- 141 (pi-), 288 +- 5 +- 23 (K+) and 241 +- 3 +- 19 (K-). The systematics of the strange to non--strange meson ratios K/pi are found to track the variation of the baryo--chemical potential with rapidity and energy. Landau--like hydrodynamics describes the bulk transport of the pions in the longitudinal direction. The rapidity densities dN/dy of pi+/- and K+/- have been measured by the BRAHMS experiment at RHIC over a broad rapidity range (-0.1 < y < 3.5) for central Au+Au collisions at sqrt(snn) = 200 GeV. The full phase--space yields are 1742 +-17 +- 140 (pi+), 1761 +- 16 +- 141 (pi-), 288 +- 5 +- 23 (K+) and 241 +- 3 +- 19 (K-). Landau--like hydrodynamic is found to describe the bulk pions in the longitudinal direction. The systematics of the strange to non--strange meson ratios K/pi are found to track the variation of the baryo--chemical potential mu_B with rapidity and energy. We can probably skip mu_B (the symbol) from the abstract.
