AI总结：
本研究通过Pb–Pb与pp碰撞中的（多）奇异强子产额及角关联测量，考察系统尺寸和事件拓扑效应，并与PYTHIA8、HERWIG7、EPOS-LHC模型比较，以揭示奇异粒子产生机制及其与硬散射和底层事件的联系。
摘要：
在LHC能量下对小碰撞系统中轻味粒子产生的测量显示，一些特征开始显现，类似于通常在核-核碰撞中观察到的现象。本文将介绍在√s_NN=5.02和5.36 TeV的Pb–Pb碰撞中关于（多）奇异强子产生的新结果。这些结果将结合ALICE实验在LHC第3运行期采集的√s=0.9和13.6 TeV pp碰撞中轻味强子产生的最新测量结果进行讨论。为理解奇异粒子产生机制，测量了多奇异强子与相关已鉴别强子之间的角关联，并与弦断裂模型PYTHIA8、团簇强子化模型HERWIG7以及核心-日冕模型EPOS-LHC的预测进行比较。此外，利用以事件中最高p_T强子为触发的双强子关联，研究了奇异强子产生与硬散射过程及底层事件之间的联系。
英文摘要：
Measurements of light-flavour particle production in small collision systems at the LHC energies have shown the onset of features that resemble what is typically observed in nucleus-nucleus collisions. New results on the (multi-)strange hadron production in Pb--Pb collisions at $\sqrt{s_{\mathrm{NN}}}$=5.02 and 5.36 TeV will be presented. These results are discussed in the context of recent measurements of light-flavour hadron production in pp collisions at $\sqrt{s}$ = 0.9 and 13.6 TeV collected by the ALICE experiment in Run 3 of the LHC. In order to understand the strangeness production mechanism, angular correlation between multi-strange and associated identified hadrons are measured and compared with predictions from the string-breaking model PYTHIA8, the cluster hadronisation model HERWIG7, and the core-corona model EPOS-LHC. In addition, the connection of strange hadron production to hard scattering processes and to the underlying event is studied, using di-hadron correlations triggered with the highest-$p_{\mathrm{T}}$ hadron in the event.
