"Bulk properties of the medium produced in relativistic heavy-ion collisions from the beam energy scan program." <i>Physical Review C,</i> 96, no. 4 (2017) American Physical Society: https://doi.org/10.1103/PhysRevC.96.044904.https://hdl.handle.net/1911/103849We present measurements of bulk properties of the matter produced in Au+Au collisions at √sNN=7.7,11.5,19.6,27, and 39 GeV using identified hadrons (π±, K±, p, and ¯p) from the STAR experiment in the Beam Energy Scan (BES) Program at the Relativistic Heavy Ion Collider (RHIC). Midrapidity (|y|<0.1) results for multiplicity densities dN/dy, average transverse momenta ⟨pT⟩, and particle ratios are presented. The chemical and kinetic freeze-out dynamics at these energies are discussed and presented as a function of collision centrality and energy. These results constitute the systematic measurements of bulk properties of matter formed in heavy-ion collisions over a broad range of energy (or baryon chemical potential) at RHIC.engArticle is made available in accordance with the publisher's policy and may be subject to US copyright law.
