摘要：

The BRAHMS collaboration has measured identified particle spectra from Au+Au collisions at root s(NN) = 200 GeV. Rapidity densities are deduced from fits to the pion and kaon spectra. dN/dy is plotted as a function of rapidity and 4 pi yields and ratios are calculated. The signed K/pi ratios are compared to values obtained at lower energies. We find that K-/pi(-) increases monotonically from the AGS and SPS regimes, while K+/pi(+) is similar to what was found at the highest root s(NN) at SPS.
