摘要：

We present STAR measurements of K-S(0), phi, Lambda, Xi, and Omega at mid-rapidity from Au+Au collisions at root 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.
