摘要

NA57实验测量了在√sNN=17.3 GeV下，固定目标Pb - Pb相互作用中，KSO、Λ和\(\bar \Lambda \)粒子的pT分布与碰撞中心性的关系。在本文中，我们研究了中心到外围核修饰因子，并将它们与其他测量和理论预测进行了比较。

First measurement of the strange particles R CP nuclear modification factors in heavy-ion collisions at the SPS

The NA57 experiment has measured the pT distributions of KSO, Λ, and \(\bar \Lambda \) particles in fixed-target Pb−Pb interactions at √sNN=17.3 GeV, as a function of the collision centrality. In this paper we study the central-to-peripheral nuclear modification factors and compare them to other measurements and to theoretical predictions.
