论文摘要
横向球体是一个事件结构变量，它提供了一种有效的方法，将数据分别分别分别为对应于具有少量多果园相互作用（MPI）事件的过程的硬和软组件。来自LHC的小型系统的最新实验结果表明，事件分类中横向球变量的导入。在这一贡献中，我们研究了$ \ sqrt {s_ {nn}} $ = 5.44 TEV的XE-XE碰撞中确定的粒子产生的动力学，并使用多相传输模型（AMPT）和最近开发的Angantyr模型，该模型融合在毕达利亚州中。对牙齿颗粒的横向动量光谱的研究进行了不同的（各向同性）和硬性（类似码头）事件的研究。
Transverse Spherocity is an event structure variable which provide an effective way to disentangle the data into hard and soft components of the processes corresponding to events with small and large numbers of multi-parton interactions (MPI), respectively. Recent experimental results in small systems from the LHC suggest the importacnce of transverse spherocity variable in the classification of the events. In this contribution, we have studied the dynamics of identified particle production in Xe-Xe collisions at $\sqrt{s_{NN}}$ = 5.44 TeV using A Multi-Phase Transport Model (AMPT) and the recently developed Angantyr model, which is incorporated within PYTHIA8. A study of the transverse momentum spectra of the dentified particles are presented for soft (isotropic) and hard (jetty-like) events in different centrality intervals.
