STAR Experiment Results from BES Program

One of the primary goals of STAR’s experimental program at the Relativistic Heavy-Ion Collider (RHIC) is the investigation of Quantum chromodynamics (QCD) phase properties. These include the search for the location of QCD critical point and the predicted first order phase transition between Quark Gluon Plasma (QGP) and hadron gas. To make a detailed scan on the phase diagram, RHIC has performed two phases of the Beam Energy Scan program colliding gold nuclei at various nucleon-nucleon center of mass energies over the range from 62.4 to 7.7 GeV in BES-I, from 54.4 to 7.7 GeV in BES-II in collider mode and from 13.7 to 3 GeV in fixed-target (FXT) mode. This report will summarize some of the results obtained from BES-I and BES-II.
