高能核碰撞中3+1D色场的时空结构

Space-time structure of 3+1D color fields in high energy nuclear collisions

Andreas Ipp, David I. Müller, Soeren Schlichting, Pragya Singh

摘要:

在高能QCD色玻璃凝聚有效场论的稀释极限下,考虑纵向伸展核的碰撞,对重离子碰撞中的色场进行了解析计算.基于未来光锥中色场的一般解析表达式,我们计算了一个简单的核碰撞几何模型中横向压力的快度分布,并将我们的结果与3+1D经典Yang-Mills模拟结果进行了比较.

英文摘要:

We perform an analytic calculation of the color fields in heavy-ion collisions by considering the collision of longitudinally extended nuclei in the dilute limit of the Color Glass Condensate effective field theory of high-energy QCD. Based on general analytic expressions for the color fields in the future light cone, we evaluate the rapidity profile of the transverse pressure within a simple specific model of the nuclear collision geometry and compare our results to 3+1D classical Yang-Mills simulations.
