Abstract

Exploring the QCD phase structure is one of the ultimate goals of high-energy heavy-ion colliding experiments. At BNL-RHIC, the Beam Energy Scan (BES-I) program was carried out from 2010 to 2014, and many data sets have been collected by the STAR experiment in various collision energies from √ s = 200 GeV down to 7.7 GeV in Au+Au collisions. In order to reduce the uncertainties in the interested energy region (7.7 < √ s< 19.6 GeV), the BESII program is scheduled for 2019-2021. In this talk, we present the BES-I results on hadron spectra, directed flow light nuclei production and higher-order cumulants of conserved charges which covers the physics issues of the freeze-out, first-order phase transition and the searching for the QCD critical point, respectively. The current status of BES-II and the future prospects for the fixed-target program will be also discussed.
