论文摘要
我们已经研究了最终奇怪粒子的横向动量（$ p_t $）光谱，包括$ k^{\ pm} $，$ ϕ $，$ \ iTT一$和$ \itΩ$，由高能铅铅（PB-PB），Proton-lead（$ p $ -pb $ -pb），Xenon-Xenon-xenon（Xenon-xenon（Xenon-xenon）（XENON-collidioned）（XECERIDISE）（XEE-XE-xe-collisiony（Xee-collisiony））（xe collisional）（xe-collisiony（Xece）collisiony（xece）考虑到多Quark组成的贡献，其概率密度分布由修改后的Tsallis-Pareto型函数描述，我们通过蒙特卡洛方法模拟了最终状态奇怪粒子的$ p_t $光谱，在大多数情况下，这证明与实验数据表现出很好的一致性。获得动力学冻结参数。目前的方法提供了一种新的工具，用于研究高能碰撞中产生的各种颗粒的光谱，更现实地反映了碰撞过程，这对于研究产生颗粒的形成和特性至关重要。
We have studied the transverse momentum ($p_T$) spectra of the final-state strange particles, including $K^{\pm}$, $ϕ$, $\itΞ$, and $\itΩ$, produced in high energy lead-lead (Pb-Pb), proton-lead ($p$-Pb), xenon-xenon (Xe-Xe) collisions at the Large Hadron Collider (LHC). Taking into account the contribution of multi-quark composition, whose probability density distribution is described by the modified Tsallis-Pareto-type function, we simulate the $p_T$ spectra of the final-state strange particles by a Monte Carlo method, which is shown to be in good agreement with the experimental data in most the cases. The kinetic freeze-out parameters are obtained. The present method provides a new tool for studying the spectra of various particles produced in high energy collisions, reflecting more realistically the collision process, which is of great significance to study the formation and properties of the produced particles.
