论文摘要
在这项研究中，我们系统地研究了TEV质量能量中心5.44的变形XE-XE碰撞。 We exploit the Monte Carlo HYDJET++ model to compute transverse momentum ($p_{T}$) distribution, nuclear modification factor $R_{AA}$ and relative suppression in terms of $R_{CP}$ as a function of transverse momentum and centrality of collision of charged hadrons in body-body and tip-tip geometrical configurations, respectively.我们已经将HYDJET ++模型结果与Alice实验数据和AMPT模型（字符串融合版本）结果进行了比较。最小偏置XE-XE碰撞表明，与中等差异的Alice实验数据相匹配。平均横向动量（$ \ langle p_ {t} \ rangle $）显示出强中心性依赖性。讨论了硬性球散射对总电荷强子产量的贡献。两个核修饰因子$ r_ {aa} $和相对抑制$ r_ {cp} $都明确地依赖中心性和横向动量。带电的强子观测值对碰撞的几何配置显示出明显的依赖性。与AMPT模型相比，HYDJET ++模型比AMPT模型更接近实验数据。
In this study, we systematically investigate deformed Xe-Xe collisions at 5.44 TeV center of mass energy. We exploit the Monte Carlo HYDJET++ model to compute transverse momentum ($p_{T}$) distribution, nuclear modification factor $R_{AA}$ and relative suppression in terms of $R_{CP}$ as a function of transverse momentum and centrality of collision of charged hadrons in body-body and tip-tip geometrical configurations, respectively. We have compared HYDJET++ model results to those from ALICE experimental data and AMPT model (String-Melting version) results. Minimum bias Xe-Xe collisions show a suitable match with ALICE experimental data at midrapidity. Average transverse momentum ($\langle p_{T} \rangle$) show strong centrality dependence. The contribution of hard parton scatterings to the total charged hadron yield is discussed. Both nuclear modification factor $R_{AA}$ and relative suppression $R_{CP}$ show a clear dependence on centrality as well as transverse momentum. The charged hadron observables show a clear dependence on the geometrical configuration of the collisions. HYDJET++ model justifies experimental data more closely than the AMPT model.
