QCD Phase Diagram：期望与挑战
The QCD Phase Diagram: Expectations and Challenges
摘要：
本文综述了QCD理论在相图方面的最新进展，特别是在高重化学势下临界点及其附近一级相变的指示，以及在高$μ_{B}$下的另一个相--夸克物质相的新观点。后一种状态可能最终解释了在低于SPS能量的能量下A+A碰撞的强子化学平衡冻结点。我们回顾了几个事件的事件波动信号，承诺揭示了一个临界点的存在，我们讨论了其可能的反射在最近的格点量子色动力学计算。
英文摘要：
A survey is given of recent QCD theory advances concerning the phase diagram, in particular the indications for a critical point and adjacent first order phase transition at high baryo-chemical potential, and the new ideas concerning a further phase at high $μ_{B}$, the quarkyonic matter phase. The latter state might finally explain the hadro-chemical equilibrium freeze-out points from A+A collisions at energies below SPS energy. We review several event-by-event fluctuation signals that promise to shed a light on the existence of a critical point, and we discuss its possible reflection in recent lattice QCD calculations.
