高$p_T$共振作为探索热和致密核物质的可能性

High $p_T$ resonances as a possibility to explore hot and dense nuclear matter

S. Vogel, J. Aichelin, M. Bleicher

摘要:

超相对论重离子实验的基本目标之一是探索高密度、高温下强相互作用物质。在这项调查中,我们特别研究的信息,可以通过分析重子和介子共振。这些共振的衰变产物携带在其衰变的时空点处的共振性质的信息。我们特别研究了在$E_{lab}$ = 30 AGeV和$\sqrt{s}$ = 200 AGeV之间的能量范围内,未来FAIR设施和目前RHIC对撞机之间的能量域的重离子碰撞的可重构共振的百分比作为密度的函数。

英文摘要:

One of the fundamental objectives of experiments with ultrarelativistic heavy ions is to explore strongly interacting matter at high density and high temperature. In this investigation we study in particular the information which can be obtained by analyzing baryonic and mesonic resonances. The decay products of these resonances carry information on the resonances properties at the space time 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 AGeV and $\sqrt{s}$ = 200 AGeV, the energy domain between the future FAIR facility and the present RHIC collider.
