Abstract
We 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.31 MoreReceived 25 January 2017DOI:https://doi.org/10.1103/PhysRevC.96.044904©2017 American Physical SocietyPhysics Subject Headings (PhySH)Research AreasParticle & resonance productionQCD phase transitionsQuark-gluon plasmaRelativistic heavy-ion collisionsThermal & statistical modelsNuclear Physics
