Abstract
Exploration of the hot and dense nuclear matter produced in collisions of heavy ions is one of the main goals of modern high energy nuclear physics. The Relativistic Heavy Ion Collider (RHIC) provides a unique opportunity to map the QCD phase diagram by colliding different nucleus species and varying the energy of collisions. RHIC has already begun the second phase of the Beam Energy Scan (BES) program, which will allow us to cover energy range for gold-gold collisions \(\sqrt {{{s}_{{NN}}}} = 7.7{\kern 1pt} - {\kern 1pt} 27\) GeV. The Fixed-target Program (FXT) will extend collision energy range available for the analysis down to \(\sqrt {{{s}_{{NN}}}} = 3.0\) GeV. BES-II along with FXT will dramatically enhance our understanding of the QCD phase diagram in the broad range of baryon chemical potential, \({{\mu }_{{\text{B}}}}\), up to 720 MeV. Recent detector upgrades increase STAR’s acceptance both in rapidity and low transverse momentum, and extend its particle identification capabilities. With new detectors STAR can explore phase diagram with even higher precision hopefully reaching both the onset of deconfinement as well as the critical point. In this talk, we present the most recent results and future plans from the STAR experiment.
