我们如何通过实验来探索解除禁闭的开始?

How can we explore the onset of deconfinement by experiment?

摘要:

量子色动力学(QCD)是描述强相互作用物理的理论,这是毋庸置疑的。QCD的格点规范模拟预言,在$μ,T$平面上有一条线,在这条线上发生了从禁闭强子物质到解除禁闭夸克的跃迁。该转变是交叉(在低$μ$)或一阶(在高$μ$)。研究$μ,T$平面上不同位置的这种相变并探索退精细相的性质是RHIC和FAIR重离子实验的目标。这是本贡献的目的是讨论一些被认为是有用的,用于此目的的观测。

英文摘要:

There is little doubt that Quantumchromodynamics (QCD) is the theory which describes strong interaction physics. Lattice gauge simulations of QCD predict that in the $μ,T$ plane there is a line where a transition from confined hadronic matter to deconfined quarks takes place. The transition is either a cross over (at low $μ$) or of first order (at high $μ$). It is the goal of the present and future heavy ion experiment at RHIC and FAIR to study this phase transition at different locations in the $μ,T$ plane and to explore the properties of the deconfined phase. It is the purpose of this contribution to discuss some of the observables which are considered as useful for this purpose.
