论文摘要
在重型离子反应中硬粒子抑制的大多数计算中，由于形成时间参数，辐射阶段被忽略了。大多数硬粒子淋浴都会在系统进入耐热的演化之前退出热且密集的培养基。在这一贡献中，提出了对硬粒子的撤销效果的HADRONIC运输方法中的首次评估（模拟许多加速的强烈相互作用的Hadron）。特别是，表明耐药的能量损失取决于粒子物种以及探针的能量。 pions给出了$ \ langle \ tilde {q} \ rangle $参数的参数化。总体而言，横向动量在2-10 GEV的范围内预计竖体阶段的重大影响可能会影响Jet子结构分析，并且（强硬）相关性可观察到可能会受到影响。
In most calculations of hard particle suppression in heavy-ion reactions the hadronic stage has been neglected due to formation time arguments. Most of the hard particle shower exits the hot and dense medium before the system enters the hadronic evolution. In this contribution, a first assessment within the hadronic transport approach SMASH (Simulating Many Accelerated Strongly-interacting Hadrons) of rescattering effects on hard particles is presented. In particular, it is shown that the hadronic energy loss depends on the particle species as well as the energy of the probe. A parametrization for the $\langle \tilde{q} \rangle$ parameter as a function of temperature and particle energy is given for pions. Overall, major effects of the hadronic stage are expected in the transverse momentum range from 2-10 GeV and therefore jet sub-structure analysis and (hard-soft) correlation observables might be affected.
