相对论重离子物理学领域最基本的问题之一是如何达到和探索跨越手性和/或非定义相变所需的密度。在这个分析中，我们研究了通过分析这种核反应中热相和密相的重子和中子共振所能收集到的信息。这些共振的衰变产物在其衰变的时空点上携带着共振特性的信息。我们特别研究了在E lab = 30 a GeV和√s = 200 a GeV之间的能量范围内重离子碰撞的可重构共振百分比作为密度的函数，该能量范围介于未来的FAIR设施和现在的RHIC对撞机之间。
One of the most fundamental questions in the field of relativistic heavy-ion physics is how to reach and explore densities which are needed to cross the chiral and/or the deconfinement phase transition. In this analysis we investigate the information we can gather by analyzing baryonic and mesonic resonances on the hot and dense phases in such nuclear reactions. The decay products of these resonances carry information on the properties of the resonances at the spacetime point of their decay. We especially investigate the percentage of reconstructable resonances as a function of density for heavy-ion collisions in the energy range between E lab = 30 A GeV and √s = 200 A GeV, the energy domain between the future FAIR facility and the present RHIC collider.
