摘　　要：能量扫描理论合作组(Beam Energy Scan Theory Collaboration,BEST)的目标是建立一个可以描述美国相对论重离子对撞机(Relativistic Heavy-Ion Collider,RHIC)上第二期能量扫描实验的动力学框架。该实验有可能找到强相互作用相图上的临界点。本文总结自2016年起,BEST合作组取得重要进展,并对未来探索中高密度区相图做了展望。Exploring the quantum chromodynamics(QCD)phase diagram at finite bayron density regime through the beam energy scan(BES)program at the relativistic heavy-ion collider(RHIC)is one of the key frontiers in high energy nuclear physics.The high precision data anticipated from the second phase of the BES program would potentially enable the discovery of the conjectured QCD critical point,a landmark point on the phase diagram.In this paper,the progress made by the beam energy scan theory(BEST)collaboration,which was formed with the goal of providing a theoretical framework for analyzing data from BESII,is reviewed.In addition,the challenge of investigating the QCD phase diagram with future facilities is discussed.
