الوصف: | We evaluate centrality dependence of hyperon, $\Lambda, \Xi, \Omega$ and $K$ meson yields from Au+Au collisions at $\sqrt{s_{NN}}$=200 GeV using rate equation and compare with experimental observations. An increase in the yield per participating nucleon is observed with centrality. Higher rate of multistrange productions compared to single-strange are also observed in case of central collisions. Using rate equation or momentum integrated Boltzmann equation we discuss the yield microscopically which are then normalised with thermal pions to get the yield ratio,($H_s+\bar{H_s}$)/($\pi^++\pi^-$) at various centralities. We have also evaluated the relative yield of anti hyperons per participant at various centralities and compared with observations made at RHIC. Increase in the rate of $\Xi$ yield compared to $\Lambda$ is realised in most central collisions. We find multi strange $\Xi,\Omega$ freeze-out at a temperature very close to $T_c$ and $\Lambda, K$ do little later. Comment: 12 pages, 5 figures |
