【 摘 要 】

We present the recent STAR results on the production of strange hadrons (K0s, φ, Λ, Ξ and ω) in √sNN= 7.7 - 39 GeV Au+Au collisions in the RHIC beam energy scan program. We investigate the strangeness enhancement and strangeness equilibration as a function of beam energy and system size at RHIC. Nuclear modification factors and particle ratios will be highlighted. Implications on partonic vs. hadronic dynamics as a function of the beam energy will be discussed.
