    Abstract

    Particle production of charged kaons in central Au+Au collisions at √SNN = 200 GeV has been studied as a function of rapidity by the BRAHMS collaboration at RHIC. The kaon spectral shapes are described well by an exponential in transverse mass for the rapidity range of 0 ≤ y K ≤ 3.3 with smoothly decreasing inverse slopes as the rapidity increases. For the charged kaon to pion ratios, while there is no significant rapidity dependence for the K++ ratio, the K -- ratio shows a significant decrease from y ≈ 1 towards higher rapidities. The systematics of K-/K+ and p̄/p ratios in the measured rapidity range demonstrates a strongly correlated behaviour which can be described by thermal-statistical models.
