【 摘 要 】

We report the measurements of the production of strange hadrons KS0, Λ and Ξ at mid rapidity in Au+Au collisions at √SNN= 14.5 GeV from the Beam Energy Scan (BES) program at the BNL Relativistic Heavy Ion Collider (RHIC). The collision energy dependence of strange hadron yields are also presented. To understand the recombination and part.on energy loss mechanisms, nuclear modification factors and baryon to meson ratios are measured and also compared with the statistical and thermal model.
