摘要：

STAR具有很高的接受度和出色的粒子识别能力，是研究高能核碰撞的最佳中快度对撞机实验之一。STAR实验提供了关于初始条件、热的稠密介质的性质以及冻结时的性质的全部信息。在$\sqrt{s_{NN}} = 200$ GeV的Au+Au碰撞中，STAR的重点是RHIC产生的sQGP的性质。为了探索QCD相图的性质，自2010年以来，该实验收集了相当大的Au+Au碰撞数据集，这些数据集位于净重子密度较大的低碰撞能量区域。在2014年夸克物质会议上，STAR实验做了16个演讲，涵盖了物理学主题，包括{ \it集体动力学}，{\it电磁探针}、{\it重口味}、{\it初始状态物理学}，{\it射流}，{\it QCD相图}，{ \it热力学和强子化学}，和{ \it未来的实验设施，升级，[1-16]的工具。在这篇综述中，我们将重点介绍STAR实验的一些结果，特别是RHIC束流能量扫描计划的最新测量结果。最后，我们将讨论STAR近期在RHIC的物理计划，而不是总结。

英文摘要：

With large acceptance and excellent particle identification, STAR is one of the best mid-rapidity collider experiments for studying high-energy nuclear collisions. The STAR experiment provides full information on initial conditions, properties of the hot and dense medium as well as the properties at freeze-out. In Au+Au collisions at $\sqrt{s_{NN}} = 200$ GeV, STAR's focus is on the nature of the sQGP produced at RHIC. In order to explore the properties of the QCD phase diagram, since 2010, the experiment has collected sizable data sets of Au+Au collisions at the lower collision energy region where the net-baryon density is large. At the 2014 Quark Matter Conference, the STAR experiment made 16 presentations that cover physics topics including {\it collective dynamics}, {\it electromagnetic probes}, {\it heavy flavor}, {\it initial state physics}, {\it jets}, {\it QCD phase diagram}, {\it thermodynamics and hadron chemistry}, and {\it future experimental facilities, upgrades, and instrumentation} [1-16]. In this overview we will highlight a few results from the STAR experiment, especially those from the recent measurements of the RHIC beam energy scan program. At the end, instead of a summary, we will discuss STAR's near future physics programs at RHIC.
