摘要:

在相对论重离子碰撞中,集体观测量对研究夸克胶子等离子体的性质起着至关重要的作用,其中初始碰撞几何信息是关键.然而,初始碰撞几何形状,例如,反应平面,在实验中不能直接提取。本文提出了利用相干光生过程的线偏振特性来确定反应平面的思想,并与传统方法进行了比较,讨论了该方法的优越性。

英文摘要:

The collective observables play critical roles in probing the properties of quark-gluon-plasma created in relativistic heavy-ion collisions, in which the information on initial collision geometry is crucial. However, the initial collision geometry, e.g., the reaction plane, cannot be directly extracted in the experiment. In this paper, we demonstrate the idea of determining the reaction plane via the feature of linear polarization of the coherent photoproduction process and discuss the advantages of the proposed approach in comparison with traditional methods.
