Abstract

We present STAR measurements of K⁰_S, ϕ, Λ, Ξ, and Ωat mid-rapidity from Au+Au collisions at √s_NN = 7.7, 11.5, 19.6, 27, and 39 GeV from the Beam Energy Scan (BES) program at the BNL Relativistic Heavy Ion Collider (RHIC). Nuclear modification factors and baryon-to-meson ratios are measured to understand recombination and parton energy loss mechanisms. Implications on partonic versus hadronic dynamics at low beam energies are discussed.
