论文摘要

基于\ angantyr模型在描述高能量重离子碰撞中harronic最终状态的多重性分布方面的最新成功,我们研究了一个基于字符串的方案可以在此类碰撞中测得的流动效应。为此,我们改善了我们以前的所谓\ textit {shoving}模型,在空间时间内接近的字符串倾向于以一种可以产生各向异性流量的方式相互排斥,我们发现该模型确实可以在Å碰撞中产生这样的流。生成的流还不足以重现测量值,但是我们确定了模型的实现中的一些缩写,后者在固定后可以可能给出更逼真的流量。

Based on the recent success of the \angantyr model in describing multiplicity distributions of the hadronic final state in high energy heavy ion collisions, we investigate how far one can go with a such a string-based scenario to describe also flow effects measured in such collisions. For this purpose we improve our previous so-called \textit{shoving} model, where strings that are close in space--time tend to repel each other in a way that could generate anisotropic flow, and we find that this model can indeed generate such flows in Å collisions. The flow generated is not quite enough to reproduce measurements, but we identify some short-comings in the presented implementation of the model that, when fixed, could plausibly give a more realistic amount of flow.
