Beam energy dependence of strange hadron production from STAR at RHIC

We present STAR measurements of image, and Ω at mid-rapidity from Au + Au collisions at image, 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.
