论文摘要
我们研究了使用强子共振气体模型在p-p，p-pb和pb-pb碰撞中看到的带电粒子多样性（$ dn_ {ch}/dy $）的带电粒子多样性（$ dn_ {ch}/dy $）的陌生产生的增加。使用基于已知相位移位分析的S-矩阵校正，使用了奇怪的规范集合，考虑了黑质校正的相互作用。由于确切的陌生保守性，我们展示了约束的基本作用，这对描述奇怪粒子产量的观察到的特征及其用$ dn_ {ch}/dy $进行缩放起来起作用。此外，提出了与S-Matrix校正的强子共振气体模型进行比较的结果。我们观察到，通过S-Matrix形式主义通过相移分析引入的相互作用对于更好地描述独立于碰撞系统的产量数据至关重要。这项工作是基于我们与让·克莱曼（Jean Cleymans）的持久合作和最新出版物。
We investigate the increase in strangeness production with charged particle multiplicity ($dN_{ch}/dy$) seen by the ALICE collaboration at CERN in p-p, p-Pb and Pb-Pb collisions using the hadron resonance gas model. The strangeness canonical ensemble is used taking into account the interactions among hadrons using S-matrix corrections based on known phase shift analyses. We show the essential role of constraints due to the exact conservation of strangeness which is instrumental to describing observed features of strange particle yields and their scaling with $dN_{ch}/dy$. Furthermore, the results on comparing the hadron resonance gas model with and without S-matrix corrections, are presented. We observe that the interactions introduced by the phase shift analysis via the S-matrix formalism are essential for a better description of the yields data independent of collision system. This work is based on our long-lasting collaboration and most recent publications with Jean Cleymans.
